Pay Versus Performance Table
As required by Item 402(v) of Regulation
S-K,
the Company is providing the following information regarding the relationship between executive compensation and the Company’s financial performance for each of the last three completed fiscal years. In determining the “compensation actually paid” (“CAP”) to the Company’s named executive officers (“NEOs”), the Company is required to make various adjustments to amounts that have been reported in the Summary Compensation Table (“SCT”), as the SEC’s valuation methods for this Pay Versus Performance Table (“PVPT”) differ from those required in the SCT. The dollar amounts reported in each column (c) below represent the amount of CAP to each principal executive officer (“PEO”), as computed in accordance with Item 402(v) of Regulation
S-K.
The dollar amounts do not reflect the actual amount of compensation earned by or paid to the applicable PEO during the applicable year. The dollar amounts reported in column (e) below represent the amount of average CAP to the
non-PEO
named executive officers, as computed in accordance with Item 402(v) of Regulation
S-K.
The dollar amounts do not reflect the actual amount of compensation earned by or paid to the
non-PEO
named executive officers during the applicable year.

Compensation Actually Paid vs. Total Shareholder Return [Text Block]
Relationship between CAP and cumulative TSR
. TSR is not a financial performance metric used by the Company to determine executive compensation for any of its named executive officers. However, as discussed in “Compensation Discussion and Analysis” in the Executive Summary section, the Company has granted RSUs and performance-based RSUs, the ultimate value of which will be tied to the Company’s stock price at the time of the respective vestings.
 
Since 2020, the
COVID-19
pandemic has had a severely negative impact on the airline industry, including, most recently, the Omicron variant in early 2022. The table below shows a comparison of annual TSRs, including cumulative TSRs, between the Company and its peer group. CAP for the Company’s NEOs generally correlated with the directional movement of TSR and, as evidenced by the table below, the Company’s TSR was generally stronger than its peer group.

Compensation Actually Paid vs. Net Income [Text Block]
Relationship between CAP and GAAP net income
. GAAP net income is not a financial performance metric directly used by the Company to determine executive compensation for any of its named executive officers. However, as discussed in “Compensation Discussion and Analysis – Determination of 2022 Executive Compensation; Analysis of Compensation Elements – Short-Term Incentive Compensation,” for 2022, GAAP net income was a component of the EBITDA calculation for determining 45% of the Scorecard results. Further, as discussed in “Compensation Discussion and Analysis – Determination of 2022 Executive Compensation; Analysis of Compensation Elements – Long-Term Incentive Compensation – Equity Awards – Performance-Based RSUs,” for 2022, Operating income (a portion of GAAP net income) is a component of the Adjusted ROIC
(after-tax)
calculation used to determine the percent of performance-based RSUs granted in 2022 that will vest in 2025.
For 2021, GAAP net income was a component of the average daily core cash burn calculation for determining 30% of the 2021 Scorecard results. Also, for 2021, GAAP net income is a component of the EBITDA calculation used to determine the percent of performance-based RSUs granted in 2021 that will vest in 2024.
Operating income (a portion of GAAP income) has also been a component of (i) the ROIC calculation used to determine the percent of performance-based RSUs granted in 2020 that were scheduled to vest in 2023, (ii) the ROIC calculation used to determine the percent of performance-based RSUs granted in 2019 that were scheduled to vest in 2022, (iii) the ROIC calculation used to determine the percent of performance-based RSUs granted in 2018 that vested in 2021, and (iv) the ROIC calculation used to determine the percent of performance-based RSUs granted in 2017 that vested in 2020. As can be observed in the PVPT, CAP for the Company’s NEOs generally correlated with the directional movement of GAAP net income.
   
Compensation Actually Paid vs. Company Selected Measure [Text Block]
Relationship between CAP and the Company Selected Measure (Adjusted ROIC
(after-tax))
. As discussed in “Compensation Discussion and Analysis,” a significant portion of the Company’s compensation for its named executive officers is in the form of performance-based RSUs. As further discussed in “Compensation Discussion and Analysis,” with respect to performance-based RSUs granted in 2022, the number of performance-based RSUs vesting and settleable in shares of common stock at the 2025 vesting date is based entirely on the Company’s achievement of Adjusted ROIC
(after-tax)
targets, and can range from zero to 300 percent of the applicable performance-based RSU stock award. For 2022, the Company achieved Adjusted ROIC
(after-tax)
of 7.6 percent, and the Company accordingly maintained its percent vesting assumption at December 31, 2022, at 100 percent of the 2022 performance-based RSU stock award for each named executive officer.
With the exception of 2021 when equity grants were made during the
COVID-19
pandemic, the Company has historically granted performance-based RSUs using a form of ROIC as the sole performance metric for determining the number of performance-based RSUs vesting and settleable in shares of common stock at the applicable vesting date. For 2021, during the pandemic, the Company chose adjusted EBITDA as the primary long-term performance metric to further align the Company’s incentive compensation with the Company’s change in primary focus to liquidity, reflecting what the Company believed would be most important to Shareholders at the time. During 2020, the Company’s equity grants took place before the start of the COVID
 
pandemic, and the Company used
after-tax
ROIC as the sole performance metric for determining the number of performance-based RSUs vesting and settleable in shares of common stock at the applicable vesting date. Those shares were scheduled to vest in February 2023, but lost all value and paid out at zero percent due to the Company’s performance results during the
COVID-19
pandemic. For 2019 and 2018, the Company used
after-tax
ROIC as the sole performance metric for determining the number of performance-based RSUs vesting and settleable in shares of common stock at the applicable vesting date. Those shares vested in February 2022 and February 2021, respectively, and paid out at zero percent and 151.3 percent, respectively. For 2017, the Company used
pre-tax
ROIC as the sole performance metric for determining the number of performance-based RSUs vesting and settleable in shares of common stock at the applicable vesting date. Those shares vested in February 2020, and paid out at 196.3 percent. Prior to 2020 and the
COVID-19
pandemic, the Company has also previously used ROIC for purposes of short-term incentive compensation. This change in the performance metric during the
COVID-19
pandemic results in a minor misalignment between Adjusted ROIC
(after-tax)
and CAP as can be observed in the PVPT, although for most NEOs compensation decreased annually during the three year period while Adjusted ROIC
(after-tax)
increased.
