The Class B Certificates will have an interest rate of 8.000% per annum and a final expected distribution date of August 15, 2025.  The offering is expected to close on July 2, 2020, subject to customary closing conditions.  The Class B Certificates will rank generally junior to the Alaska Air Class A Pass Through Certificates, Series 2020-1A (the &#8220;Class A Certificates&#8221;), which are expected to be issued concurrently with the Class B Certificates, and the Class B Certificates will not be issued unless such Class A Certificates are simultaneously issued.  </span></div><div><span><br/></span></div><div><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:150%;">The Class B Certificates will represent an interest in the assets of a pass through trust, which will hold certain equipment notes to be issued by the Issuers. Such equipment notes are expected to be secured by 26 Boeing 737-890 aircraft, each delivered new to Alaska Airlines from January 2007 to June 2010, 16 Boeing 737-990ER aircraft, each delivered new to Alaska Airlines from February 2016 to March 2019, and 19 Embraer E175 LR aircraft, each delivered new to Horizon from June 2017 to December 2018. The Issuers will use the proceeds from the issuance of the equipment notes with respect to such aircraft for general corporate purposes and to pay fees and expenses relating to this offering. The payment obligations of the Issuers under the equipment notes acquired by the pass through trust for the Class B Certificates will be fully and unconditionally guaranteed by the Company. In addition, Alaska Airlines will provide a guarantee of the payment obligations of Horizon under the equipment notes issued by Horizon held by the pass through trust for the Class B Certificates, and Horizon will also provide a guarantee of the payment obligations of Alaska Airlines under the equipment notes issued by Alaska Airlines held by the pass through trust for the Class B Certificates.</span></div><div><span><br/></span></div><div><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:150%;">The offer and sale of the Class B Certificates have not been, and the Class B Certificates will not be, registered under the Securities Act of 1933, as amended (the &#8220;Securities Act&#8221;), or the securities laws of any other jurisdiction.
