offering by Southwest Airlines Co. of $2.0&nbsp;billion aggregate principal amount of 1.250% Convertible Senior Notes due 2025, which we refer to in this prospectus supplement as the &#147;notes.&#148; The notes will bear interest at the rate of
1.250% per year and will mature on May&nbsp;1, 2025, unless repurchased or converted prior to the maturity date. Interest on the notes is payable semi-annually in arrears on May&nbsp;1 and November&nbsp;1 of each year, beginning on November&nbsp;1,
2020. </P> <P STYLE="margin-top:2pt; margin-bottom:0pt; text-indent:3%; font-size:7.5pt; font-family:Times New Roman">Holders may convert their notes at their option at any time prior to the close of business on the business day immediately
preceding February&nbsp;1, 2025, only under the following circumstances: (1)&nbsp;during any calendar quarter commencing after the calendar quarter ending on June&nbsp;30, 2020 (and only during such calendar quarter), if the last reported sale price
of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the
conversion price on each applicable trading day; (2)&nbsp;during the five business day period after any ten consecutive trading day period (the &#147;measurement period&#148;) in which the trading price (as defined below) per $1,000 principal amount
of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day; or (3)&nbsp;upon the occurrence of specified corporate
events. On or after February&nbsp;1, 2025, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their notes at any time, regardless of the foregoing circumstances. Upon
conversion, we will pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election, as described in this prospectus supplement. </P>
<P STYLE="margin-top:2pt; margin-bottom:0pt; text-indent:3%; font-size:7.5pt; font-family:Times New Roman">The conversion rate will initially be 25.9909 shares of common stock per $1,000 principal amount of notes (equivalent to an initial conversion
price of approximately $38.48 per share of common stock). The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. In addition, following certain corporate events that occur prior
to the maturity date, we will increase the conversion rate for a holder who elects to convert its notes in connection with such a corporate event in certain circumstances. </P>
<P STYLE="margin-top:2pt; margin-bottom:0pt; text-indent:3%; font-size:7.5pt; font-family:Times New Roman">In the event of a fundamental change, as defined in this prospectus supplement, the holders may require us to purchase for cash all or a
portion of their notes at a purchase price equal to 100% of the principal amount of the notes, plus accrued and unpaid interest, if any. We may not redeem the notes at our option prior to the maturity date. </P>
<P STYLE="margin-top:2pt; margin-bottom:0pt; text-indent:3%; font-size:7.5pt; font-family:Times New Roman">The notes will be unsecured and unsubordinated obligations of the Company and will rank equally with all of its other unsubordinated
indebtedness. The notes will not be entitled to the benefit of any sinking fund. </P> <P STYLE="margin-top:2pt; margin-bottom:0pt; text-indent:3%; font-size:7.5pt; font-family:Times New Roman">We do not intend to apply to list the notes on any
securities exchange or any automated dealer quotation system. Our common stock is listed on the New York Stock Exchange under the symbol &#147;LUV.&#148; On April&nbsp;28, 2020, the last reported sales price of our common stock on the New York Stock
Exchange was $29.69 per share. </P> <P STYLE="margin-top:2pt; margin-bottom:0pt; text-indent:3%; font-size:7.5pt; font-family:Times New Roman">Concurrently with this offering, we are conducting a public offering (the &#147;Concurrent Common Stock
Offering&#148;) of 70,000,000 shares of our common stock (or up to 80,500,000 shares of our common stock if the underwriters in the Concurrent Common Stock Offering exercise their option to purchase additional shares of common stock in full).
Neither this offering of the notes nor the Concurrent Common Stock Offering is conditioned upon the completion of the other, so it is possible that this offering occurs and the Concurrent Common Stock Offering does not occur, and vice versa. We
cannot assure you that the Concurrent Common Stock Offering will be completed on the terms described herein, or at all. The Concurrent Common Stock Offering is being made pursuant to a separate prospectus supplement and nothing contained herein
shall constitute an offer to sell or the solicitation of an offer to buy common stock to be issued in the Concurrent Common Stock Offering. See &#147;Concurrent Common Stock Offering.&#148; </P>

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Southwest Airlines Co. operates Southwest Airlines, a major passenger airline that provides scheduled air transportation in the United States
and near-international markets. We commenced service on June&nbsp;18, 1971, with three Boeing 737 aircraft serving three Texas cities: Dallas, Houston, and San Antonio. At March&nbsp;31, 2020, we had 742 Boeing 737 aircraft in our fleet. In peak
travel seasons during 2019, Southwest operated more than 4,000 weekday departures among a network of 101 destinations in the United States and 10 additional countries. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our financial results have been significantly affected by the <FONT STYLE="white-space:nowrap">COVID-19</FONT> pandemic, as demand for both
business and leisure air travel has declined considerably. The extent of the impact of the <FONT STYLE="white-space:nowrap">COVID-19</FONT> pandemic on our financial performance will depend on future developments, including the duration, spread,
severity, and any recurrence, of the <FONT STYLE="white-space:nowrap">COVID-19</FONT> pandemic; the duration and scope of related government orders and restrictions; and the extent of the impact of <FONT STYLE="white-space:nowrap">COVID-19</FONT> on
overall demand for air travel, all of which are highly uncertain and cannot be predicted. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Air travel is also significantly affected by
general economic conditions, the amount of disposable income available to consumers, unemployment levels, corporate travel budgets, fears or actual outbreaks of infectious disease, extreme or severe weather and natural disasters, fears of terrorism
or war, and other factors beyond our control. These and other factors, such as the price of jet fuel in some periods, the nature of our fuel hedging program, and the periodic volatility of commodities used by us for hedging jet fuel, have created,
and may continue to create, significant volatility in our financial results. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Additional information about us is included in our reports

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><I>Investing in the notes involves a high degree of risk. You should consider carefully the risks described below and discussed under the

prospectus, and the information and documents incorporated by reference in this prospectus supplement and the accompanying prospectus, and any free writing prospectus that we have authorized for use in connection with this offering before you make a
decision to invest in the notes. If any of the following events actually occurs, our business, operating results, prospects or financial condition could be materially and adversely affected. This could cause the trading price of the notes to
decline, and you may lose all or part of your investment. </I></P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Risks Relating to the Notes </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B><I>The notes are subject to prior claims of secured creditors, and if a default occurs we may not have sufficient funds to fulfill our
obligations under the notes. </I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The notes are our general unsecured obligations, ranking equally with our other senior unsecured
indebtedness and liabilities but effectively ranking below our secured indebtedness and structurally ranking below any debt and other liabilities of our subsidiaries. As of March&nbsp;31, 2020, we had $2.5&nbsp;billion of secured indebtedness. On
April&nbsp;1, 2020, we drew an additional $2.3&nbsp;billion under the Amended and Restated <FONT STYLE="white-space:nowrap">364-Day</FONT> Credit Agreement, and on April&nbsp;24, 2020 we drew an additional $350&nbsp;million under the
$417&nbsp;million accordion feature. The indenture governing the notes permits us and our subsidiaries to incur additional secured debt. If we incur any additional secured debt, our assets and the assets of our subsidiaries that are security for
that debt will be subject to prior claims by our secured creditors. In the event of our bankruptcy, liquidation, reorganization, or other winding up, assets that secure debt will be available to pay obligations on the notes only after all debt
secured by those assets has been repaid in full. Holders of the notes will participate in our remaining assets ratably with all of our unsecured and unsubordinated creditors, including our trade creditors. </P>

entitled to share ratably with the holders of the notes in any proceeds distributed upon our insolvency, liquidation, reorganization, dissolution, or other winding up. This may have the effect of reducing the amount of proceeds paid to you. If there
are not sufficient assets remaining to pay all of these creditors, all or a portion of the notes then outstanding would remain unpaid. </P>

ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness, including the notes, or to make cash payments in connection with any conversions of the notes, depends on our future performance, which is
subject to economic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to service our debt and make necessary capital expenditures. If we are
unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our
indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt

also implement this type of strategy by entering into swaps on our common stock in lieu of or in addition to short selling the common stock underlying the notes. </P>

adopt additional rules and take other actions, that may impact those engaging in short selling activity involving equity securities (including our common stock). Such rules and actions include Rule&nbsp;201 of SEC Regulation SHO, the adoption by the
Financial Industry Regulatory Authority, Inc., or FINRA, and the national securities exchanges of a &#147;Limit <FONT STYLE="white-space:nowrap">Up-Limit</FONT> Down&#148; program, the imposition of market-wide circuit breakers that halt trading of
securities for certain periods following specific market declines, and the implementation of certain regulatory reforms required by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. Any governmental or regulatory action that
restricts the ability of investors in, or potential purchasers of, the notes to effect short sales of our common stock, borrow our common stock, or enter into swaps on our common stock could adversely affect the trading price and the liquidity of

for the notes is that the equity component is required to be included in the additional <FONT STYLE="white-space:nowrap">paid-in</FONT> capital section of stockholders&#146; equity on our consolidated balance sheet, and the value of the equity
component would be treated as debt discount for purposes of accounting for the debt component of the notes. As a result, we will be required to record a greater amount of <FONT STYLE="white-space:nowrap">non-cash</FONT> interest expense in all
periods presented as a result of the amortization of the discounted carrying value of the notes to their face amount over the terms of the notes. We will report lower net income (or larger net losses) in our financial results because ASC <FONT

currently accounted for utilizing the treasury stock method, the effect of which is that the shares issuable upon conversion of the notes are not included in the calculation of diluted earnings per share except to the extent that the conversion
value of the notes exceeds their principal amount. Under the treasury stock method, for diluted earnings per share purposes, the transaction is accounted for as if the number of shares of common stock that would be necessary to settle such excess,

draft that proposes to change the accounting for such convertible debt instruments as described above. Under the exposure draft, an entity may no longer be required to separately account for the liability and equity components of convertible debt
instruments. This could have the impact of reducing <FONT STYLE="white-space:nowrap">non-cash</FONT> interest expense, and thereby increasing net income (or decreasing net losses). Additionally, as currently proposed, the treasury stock method for
calculating earnings per share will no longer be allowed for convertible debt instruments whose principal amount may be settled using shares. Rather, the <FONT STYLE="white-space:nowrap">if-converted</FONT> method may be required, which could
decrease our diluted earnings per share. We cannot be sure that the proposed changes in this exposure draft will be adopted, or will be adopted in their current format. We also cannot be sure whether other changes may be made to the current

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In late 2019, an outbreak of <FONT STYLE="white-space:nowrap">COVID-19</FONT> was identified in Wuhan, China. The <FONT
STYLE="white-space:nowrap">COVID-19</FONT> outbreak has since spread and grown globally, including within the United States and, in March 2020, the President of the United States declared a national emergency. Demand for both business and leisure
air travel has declined significantly due to the <FONT STYLE="white-space:nowrap">COVID-19</FONT> pandemic, and we have responded by reducing our published flight schedule; instituting a hiring freeze; offering voluntary leave options for Employees;
and aggressively evaluating all capital spending, discretionary spending, and <FONT STYLE="white-space:nowrap">non-essential</FONT> costs for near-term cost reductions or deferrals. The extent of the impact of the
<FONT STYLE="white-space:nowrap">COVID-19</FONT> pandemic on our business and our financial and operational performance will depend on future developments, including the duration, spread, severity, and any recurrence of the <FONT
STYLE="white-space:nowrap">COVID-19</FONT> pandemic; the duration and scope of related federal, state, and local government orders and restrictions; the extent of the impact of the <FONT STYLE="white-space:nowrap">COVID-19</FONT> pandemic on overall
demand for air travel; and our access to capital, all of which are highly uncertain and cannot be predicted. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The <FONT
STYLE="white-space:nowrap">COVID-19</FONT> pandemic has caused public health officials to recommend precautions to mitigate the spread of the virus. Federal, state, and local authorities have imposed self-quarantine requirements, issued directives
forcing businesses to temporarily close, restricted international air travel, and issued <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">shelter-in-place</FONT></FONT> and similar orders limiting the movement of individuals.
Additionally, businesses have restricted <FONT STYLE="white-space:nowrap">non-essential</FONT> travel for their employees. Such measures have depressed demand for air travel, disrupted our operations, and materially adversely affected our business.
The cancellation of flights, both in March 2020 and for future periods, has resulted in a significant amount of cash refunds and the issuance of travel credits to customers. The total value of refunds, excluding taxes and related fees, issued to
customers during March 2020 was $248 million. As of April&nbsp;24th, the total value of refunds, excluding taxes and related fees, issued to customers month-to-date April&nbsp;2020 was roughly half of March 2020 levels. Further, due to the fears and
restrictions involved with travel in the near term, sales of tickets for future travel have been well below our expectations. The cancellations and cash refunds have negatively affected our revenues and liquidity, and we expect such negative effects
to continue. We will continue to be materially adversely affected if government authorities extend existing orders or impose new orders or other restrictions intended to mitigate the spread of <FONT STYLE="white-space:nowrap">COVID-19,</FONT> if
businesses continue to restrict nonessential travel for their employees, or if fear of travel continues to depress future ticket sales. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Certain of our Employees, and employees of our suppliers and service providers, including airport and air traffic personnel, have tested
positive for or been suspected of having <FONT STYLE="white-space:nowrap">COVID-19.</FONT> These cases have resulted in the closure of facilities, reduction in available staffing, and disruptions to our overall operations. Additional instances of
actual or perceived risk of infection among our Employees, or our suppliers&#146; or service providers&#146; employees, could further negatively impact our operations. We could also be materially adversely affected if we are unable to effectively
address employment-related matters, or maintain satisfactory relations with our Employees or our Employees&#146; Representatives. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Moreover, the ability to attract and retain passengers depends, in part, upon the perception and reputation of us and the public&#146;s
concerns regarding the health and safety of travel generally, especially regarding airline travel. Actual or perceived risk of infection on our flights could have a material adverse effect on the public&#146;s perception of us, which could harm our
reputation and business. We expect that we will continue to incur <FONT STYLE="white-space:nowrap">COVID-19</FONT> related costs as we sanitize airplanes and implement additional hygiene-related protocol to airplanes, and take other action to limit
infection among our Employees and passengers. In addition, the industry may be subject to enhanced health and hygiene requirements in attempts to counteract future outbreaks, which requirements may be costly and take a significant amount of time to
implement. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The <FONT STYLE="white-space:nowrap">COVID-19</FONT> pandemic may also materially and
adversely affect our supply chain. For example, we are dependent on Boeing as our sole supplier for many of our aircraft parts. See &#147;Item 1A. Risk Factors&#151;The Company is currently dependent on Boeing as the sole manufacturer of the
Company&#146;s aircraft. Further prolonged grounding by the FAA of the Boeing 737 MAX aircraft could materially and adversely affect the Company&#146;s business plans, strategies, and results of operations&#148; and &#147;Management&#146;s

our relationship with Boeing. We are also dependent on (i)&nbsp;sole or limited suppliers for aircraft engines and certain other aircraft parts, equipment, and services, (ii)&nbsp;third party vendors, and (iii)&nbsp;service providers. The <FONT
STYLE="white-space:nowrap">COVID-19</FONT> pandemic could result in performance problems, ceased operations, or bankruptcies among these suppliers, third party vendors, and service providers. If a supplier, third party vendor, or service provider is
unable to timely provide adequate products or support for its products, or otherwise fulfill its commitments to us, our operations could be materially adversely affected. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The effects of the <FONT STYLE="white-space:nowrap">COVID-19</FONT> pandemic on the financial markets may materially and adversely affect our
access to capital and cost of capital, including our ability to raise funds through equity or debt financings. The <FONT STYLE="white-space:nowrap">COVID-19</FONT> pandemic has resulted in significant disruption of global financial markets, which
has negatively impacted the value of our common stock and our debt ratings and could negatively affect our liquidity. For example, as a result of the economic effects of the <FONT STYLE="white-space:nowrap">COVID-19</FONT> pandemic, in March and
April 2020, Moody&#146;s, S&amp;P Global, and Fitch downgraded our senior unsecured debt ratings and S&amp;P Global and Fitch downgraded our issuer ratings. In addition, all three rating agencies placed our ratings on review for further downgrade.
If our credit ratings were to be further downgraded, or general market conditions were to ascribe higher risk to our rating levels, the airline industry, or us, our access to capital and the cost of any debt financing will be negatively affected. In
addition, in response to liquidity concerns related to the <FONT STYLE="white-space:nowrap">COVID-19</FONT> pandemic and breaking with historical practice, we have recently taken on shorter-term debt in the form of our Amended and Restated <FONT
STYLE="white-space:nowrap">364-Day</FONT> Credit Agreement and secured both our Amended and Restated <FONT STYLE="white-space:nowrap">364-Day</FONT> Agreement and our Amended and Restated Revolving Credit Agreement. Further, we have taken government
assistance under the CARES Act, which requires us to comply with related restrictive provisions, including limitations on share buybacks and dividends, limitations on executive compensation, and other requirements described in &#147;We have agreed
to certain restrictions on our business by accepting financing under the CARES Act&#148; below. We continue to evaluate potential sources of additional liquidity in the short-term. The terms of future debt agreements could include more restrictive
covenants or require incremental collateral, which may further restrict our business operations. The extent to which the <FONT STYLE="white-space:nowrap">COVID-19</FONT> outbreak affects our earnings and liquidity will depend, in part, on our
ability to successfully access capital. There is no guarantee that debt or equity financings will be available in the future to fund our obligations, or that they will be available on terms consistent with our expectations. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In addition, the <FONT STYLE="white-space:nowrap">COVID-19</FONT> pandemic has significantly increased economic and demand uncertainty. The
current outbreak and continued spread of <FONT STYLE="white-space:nowrap">COVID-19</FONT> could cause a global recession, which would have a further adverse impact on our medium- and long-term financial condition and operations. Historically,
unfavorable U.S. economic conditions have driven changes in travel patterns, including reduced spending for both leisure and business travel. Unfavorable economic conditions, when low fares are often used to stimulate traffic, have also historically
hampered the ability of airlines to raise fares to counteract any increases in fuel, labor, and other costs. Any significant increases in unemployment in the United States and other regions due to the adoption of social distancing and other policies
to slow the spread of the virus would likely continue to have a negative impact on passenger bookings, and these effects could exist for an extensive period of time. The <FONT STYLE="white-space:nowrap">COVID-19</FONT> pandemic continues to rapidly
evolve. The ultimate impact of the <FONT STYLE="white-space:nowrap">COVID-19</FONT> pandemic is highly uncertain and subject to change. </P>

applicable accounting standards require separate accounting for the debt and equity components of convertible notes that, like the notes we are offering, can be settled partially or fully in cash upon conversion. We expect the initial carrying
amount of the debt component of the notes, which will be reflected as a liability on our balance sheet, to be the fair value of a similar debt instrument that does not have a conversion feature (that is, the present value of the principal and
interest payments on the notes, discounted using an interest rate equal to our cost of capital for straight, unconvertible debt), net of issuance costs attributable to the debt component. The excess of the net proceeds of the notes over this initial
liability carrying amount will be deemed to be the equity component of the notes. We expect to record the amount of the equity component as an increase to capital in excess of par value in the stockholders&#146; equity section of our balance sheet
and as a debt discount on the notes for accounting purposes. This debt discount will be amortized into interest expense over the term of the notes. As a result of this amortization, the interest expense that we expect to recognize for the notes for
accounting purposes will be greater than the cash interest payments we will pay on the notes, which will result in lower reported net income or larger reported net loss. Future accounting standards may change the manner in which we reflect the notes
in our financial statements. </P></TD></TR></TABLE>

settlement method with respect to conversions with different conversion dates. That is, prior to February&nbsp;1, 2025, we may choose for notes converted on one conversion date to settle conversions using one settlement method (e.g., physical

timely elect combination settlement with respect to a conversion but do not timely notify in writing the converting holder, with a copy to the trustee and the conversion agent (if other than the trustee), of the applicable specified dollar amount

specified dollar amount will not constitute a default under the indenture. It is our current intent and policy to settle conversions through combination settlement with a specified dollar amount per $1,000 principal amount of notes of $1,000. </P>

addition, we may, by sending written notice to the holders, irrevocably fix the settlement method to any settlement method that we are then permitted to elect that will apply to all note conversions with a conversion date that is on or after the
date we send such notice. Notwithstanding the foregoing, no such change in the default settlement method or irrevocable election will affect any settlement method theretofore elected (or deemed to be elected) with respect to any note pursuant to the
provisions described in this &#147;&#151;Conversion Rights&#151;Settlement upon Conversion&#148; section. For the avoidance of doubt, such an irrevocable election, if made, will be effective without the need to amend the indenture or the notes,

applicable law. Accordingly, the ability of a holder of the notes to require us to repurchase its notes as a result of the sale, lease or other transfer of less than all of our assets may be uncertain. </P>

Related to the Notes&#151; We may not have the ability to raise the funds necessary to repurchase the notes for cash upon a fundamental change or to settle for cash conversions of the notes, and our future debt may contain limitations on our ability
to pay cash upon conversion or repurchase of the notes.&#148; If we fail to repurchase the notes when required following a fundamental change, we will be in default under the indenture. In addition, we have, and may in the future incur, other

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The following discussion summarizes material U.S. federal income tax considerations of the acquisition, ownership and disposition of the notes
and the shares of our common stock into which the notes may be converted. The discussion below is based upon the provisions of the Internal Revenue Code of 1986, as amended (the &#147;Code&#148;), and U.S. Treasury regulations promulgated
thereunder, judicial authority and administrative interpretations, all as of the date hereof, and all of which are subject to change, possibly with retroactive effect, or are subject to different interpretations. We cannot assure you that the
Internal Revenue Service (the &#147;IRS&#148;) will not challenge one or more of the tax consequences described in this discussion, and we have not obtained, nor do we intend to obtain, a ruling from the IRS with respect to the U.S. federal income
tax consequences of acquiring, owning or disposing of the notes or our common stock into which the notes may be converted. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">This

or similar persons or organizations acting in the capacity of underwriters, placement agents, or wholesalers) and who hold the notes or our common stock as capital assets (generally, property held for investment). This discussion does not address
any U.S. federal tax considerations other than U.S. federal income tax considerations (such as U.S. federal estate and gift tax considerations), or the tax considerations arising under the laws of any foreign, state, local or other jurisdiction or
any income tax treaty. In addition, this discussion does not address all tax considerations that may be important to a particular holder in light of the holder&#146;s particular circumstances, or to certain categories of holders that may be subject

<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">We intend to take the position that the notes are securities for U.S. federal income tax purposes and that, as a result, the
exchange would be treated as a recapitalization of the notes in exchange for our common stock and cash. Under such circumstances, you would recognize capital gain, but not loss, equal to the lesser of (i)&nbsp;the excess of the sum of the fair
market value of the common stock and the amount of cash received (other than amounts of cash or stock attributable to accrued but unpaid interest, which will be taxable as ordinary interest income to the extent you have not previously included the
accrued interest in income) over your adjusted tax basis in the notes, and (ii)&nbsp;the amount of cash received by you (excluding cash paid in lieu of fractional shares, which will be treated as described in &#147;&#151;Fractional Shares&#148;
below, and cash attributable to accrued interest). </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">Except as described below under &#147;&#151;Alternative Treatment of
Conversion as Part Sale and Part Conversion,&#148; the tax basis in the shares of common stock received (including any fractional share deemed received) by you upon conversion of the notes (other than common stock received by you that is
attributable to accrued but unpaid interest, the tax basis of which would equal the amount of accrued interest with respect to which the common stock was received) will be equal to your aggregate adjusted tax basis in the notes converted, reduced by
the amount of any cash received (other than cash received in lieu of a fractional share or cash attributable to accrued but unpaid interest), and increased by the amount of gain, if any, recognized (other than with respect to a fractional share).
</P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">The holding period for the shares of common stock received by you upon conversion of the notes generally will include the
period during which you held the notes prior to the conversion, except that the holding period of any common stock received by you with respect to accrued but unpaid interest will commence on the day after the date of receipt. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">If the conversion of a note into cash and common stock were not treated as a recapitalization as discussed above, the cash
payment received may be treated as proceeds from the sale of a portion of the note and taxed in the manner described above under &#147;&#151;Disposition of the Notes,&#148; in which case our common stock received on such a conversion (other than
common stock attributable to accrued but unpaid interest, which would be taxable as interest to the extent you have not previously included the accrued interest in income) would be treated as received upon a conversion of the other portion of the
notes, which generally would not be taxable to you. In that case, your adjusted tax basis in the note would generally be allocated pro rata between our common stock received and the portion of the note that is treated as sold for cash based on the
fair market value of our common stock and the cash. The holding period for our common stock received in the conversion would include your holding period for the note, except that the holding period of any common stock received with respect to
accrued but unpaid interest would commence on the day after our common stock is received. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman"><I>Fractional Shares </I></P>

fractional share and generally will result in recognition of capital gain or loss equal to the difference between the amount of cash received by you and your tax basis in the fractional share (computed as described above). </P>

conversion rate of the notes will be adjusted in certain circumstances as described in &#147;Description of Notes&#151;Conversion Rights&#151;Conversion Rate Adjustments.&#148; Adjustments (or failures to make adjustments) that have the effect of
increasing your proportionate interest in our assets or earnings may in some circumstances result in a deemed distribution to you even though no cash is received. Adjustments to the conversion rate made pursuant to a bona fide reasonable adjustment
formula that has the effect of preventing the dilution of the interest of the holders of the notes, however, will generally not be considered to result in a deemed distribution to you. Certain of the possible conversion rate adjustments provided in
the notes (including, without limitation, adjustments in respect of taxable dividends to holders of our common stock) will not qualify as being pursuant to a bona fide reasonable adjustment formula. If such adjustments are made, you will be deemed
to have received a distribution even though you have not received any cash or property as a result of such adjustments. In addition, an adjustment to the conversion rate in connection with a make-whole fundamental change may be treated as a deemed
distribution. In certain circumstances, the failure to make an adjustment to the conversion rate may result in a deemed distribution to you if, as a result of such failure, your proportionate interest in our assets or earnings and profits is
increased. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Any deemed distributions will be treated as taxable as a dividend to the extent of our current or accumulated earnings and
profits, computed under U.S. federal tax principles, and thereafter as return of capital, or capital gain to the extent the deemed distribution exceeds your adjusted basis in the notes. You should consult your own tax advisor regarding whether any
dividend deemed paid to you would be eligible for the preferential rates of U.S. federal income tax applicable in respect of certain dividends received and, if you are a corporate U.S. holder, whether you would be entitled to claim the
dividends-received deduction with respect to any such constructive dividends. Generally, a U.S. holder&#146;s adjusted tax basis in a note will be increased to the extent any such deemed distribution is treated as a dividend. Because a constructive
dividend deemed received by a U.S. holder would not give rise to any cash from which any applicable withholding tax could be satisfied, if backup withholding is applicable to a U.S. holder (because such U.S. holder failed to establish an exemption
from backup withholding taxes as further described below in &#147;&#151;Information Reporting and Backup Withholding&#148;), any future payments of cash or common stock on the notes may be used to satisfy such backup withholding. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We are currently required to report the amount of any deemed distributions on our website or to the IRS and to holders of notes not exempt
from reporting. On April&nbsp;12, 2016, the IRS proposed U.S. Treasury regulations addressing the amount and timing of such deemed distributions and certain obligations of withholding agents and filing and notice obligations of issuers with respect
to such deemed distributions. If adopted as proposed, the regulations would generally provide that (i)&nbsp;the amount of a deemed distribution is the excess of the fair market value of the right to acquire common stock immediately after the
conversion rate adjustment over the fair market value (determined immediately after the conversion rate adjustment) of the right to acquire common stock without the conversion rate adjustment, (ii)&nbsp;the deemed distribution occurs at the earlier
of the date the conversion rate adjustment occurs under the terms of the note and the date of the actual distribution of cash or property that results in the deemed distribution and (iii)&nbsp;we may be required to report the amount of any deemed
distributions on our website or to the IRS and all U.S. holders of our notes (including holders that would otherwise be exempt from reporting). The final regulations will be effective for deemed distributions occurring on or after the date of
adoption, but U.S. holders of the notes may rely on them prior to that date under certain circumstances. You are urged to consult your own tax advisor regarding the potential effects of the proposed regulations on a purchase of the notes. </P>

recognize gain or loss equal to the difference between the amount realized and your tax basis in our common stock. Any gain or loss recognized on a taxable disposition of our common stock will be capital gain or loss. Such capital gain or loss will
be long-term capital gain or loss if your holding period at the time of the sale, redemption or other taxable disposition of our common stock is more than one year. Long-term capital gains of individuals, estates, and trusts currently are eligible
for reduced rates of U.S. federal income tax. The deductibility of capital losses may be subject to limitation. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>Possible Effect of a Consolidation

Mergers and Similar Events&#148;). Depending on the circumstances, a change in the obligor of the notes as a result of the consolidation or merger could result in a deemed taxable exchange to a U.S. holder and the modified note could be treated as
newly issued at that time, potentially resulting in the recognition of taxable gain or loss. Furthermore, if the notes were to become exchangeable into stock of an entity other than the obligor, such an exchange would generally be a taxable event.

certified under penalties of perjury, as well as certain other information or otherwise establish an exemption from backup withholding. Backup withholding is not an additional tax. Any amount withheld under the backup withholding rules is allowable
as a credit against your U.S. federal income tax liability, if any, and a refund may be obtained from the IRS if the amounts withheld exceed your actual U.S. federal income tax liability and you timely provide the required information or appropriate

that constitute &#147;forward-looking statements&#148; within the meaning of Section&nbsp;27A of the Securities Act of 1933 and Section&nbsp;21E of the Securities Exchange Act of 1934. Forward-looking statements are based on, and include statements
about, Southwest&#146;s estimates, expectations, beliefs, intentions and strategies for the future, and the assumptions underlying these forward-looking statements. Specific forward-looking statements can be identified by the fact that they do not
relate strictly to historical or current facts and include, without limitation, words such as &#147;believe,&#148; &#147;anticipate,&#148; &#147;expect,&#148; &#147;intend,&#148; &#147;may,&#148; &#147;will,&#148; &#147;estimate,&#148;

these differences are set forth in our filings with the SEC that are incorporated in this prospectus by reference or that are stated in a prospectus supplement to this prospectus under the caption &#147;Risk Factors.&#148; Caution should be taken
not to place undue reliance on the company&#146;s forward-looking statements, which represent the company&#146;s views only as of the dates of the respective documents. The company undertakes no obligation to update publicly or revise any

the trustee can enforce your rights against us if we default. There are some limitations on the extent to which the trustee acts on your behalf, described later in this section under &#147;Default and Related Matters &#151; Remedies if an Event of
Default Occurs.&#148; Second, the trustee performs administrative duties for us, such as sending you interest payments, transferring your debt securities to a new buyer if you sell, and sending you notices. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The indenture and its associated documents contain the full legal text of the matters described in this section. The indenture and the debt

entirety by reference to all the provisions of the indenture, including definitions of certain terms used in the indenture. In this summary, we describe the meaning for only the more important terms. You must look to the indenture for the most

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We may issue the debt securities as original issue discount securities, which will be offered and sold at a substantial discount below their

matter at a meeting of shareholders at which a quorum is present; provided that, for purposes thereof, all abstentions and broker nonvotes shall not be counted as voted either for or against such matter. Directors shall be elected by a majority of
the votes cast by the holders of shares entitled to vote in the election of directors at a meeting of shareholders at which a quorum is present; provided that, if the number of nominees exceeds the number of directors to be elected, directors shall
be elected by a plurality of the votes cast. For purposes thereof, (i)&nbsp;a majority of the votes cast means that the number of votes cast for a director must exceed the number of votes cast against that director, and (ii)&nbsp;abstentions and
