Item 1.01 Entry into a Material Definitive Agreement.

On March 24, 2021, Southwest Airlines Co. ("Southwest" or the "Company") entered into Supplemental Agreement No. 12 (the "Supplement") to its Purchase Agreement No. 3729 with The Boeing Company ("Boeing") relating to Southwest's purchase of Boeing Model 737 MAX 7 ("MAX 7") and 737 MAX 8 ("MAX 8") aircraft (collectively, "MAX aircraft"). Pursuant to the Supplement (i) Southwest added 100 firm orders for the MAX 7, with the first 30 to be delivered in 2022; (ii) Southwest added 155 MAX aircraft options; (iii) the order book was extended to include deliveries through 2031; and (iv) Southwest converted 70 MAX 8 firm orders to MAX 7 firm orders. The Supplement also includes certain confidential credits, discounts, and other concessions provided to Southwest by Boeing.

The Company now estimates its contractual aircraft capital spending for all years 2021 through 2026, which consists of 169 MAX firm orders from Boeing (135 MAX 7 and 34 MAX 8 aircraft), to be approximately $5.1 billion. The Company’s estimated contractual aircraft capital spending is immaterial in 2021 and approximately $700 million in 2022 (net of progress payments made on undelivered MAX aircraft and previously agreed upon delivery credits provided by Boeing to the Company). The Company continues to estimate its 2021 capital expenditures to be no more than $500 million, driven primarily by technology, facilities, and operational investments.

As a result of the Supplement, Southwest has the following contractual firm deliveries and options for Boeing 737 MAX 7 and 737 MAX 8 aircraft as follows:

1. The Company has flexibility to designate firm orders or options as MAX 7 or MAX 8, upon written advance notification as stated in the contract.

2. The 9 additional MAX 8 aircraft shown above are leases to be acquired from various third parties. The Company also received 7 leased MAX 8 aircraft in fourth quarter 2020, for a total of 16 MAX 8 operating leased aircraft from third parties in 2020 and 2021, combined.
