Insights

Financial Analyst

TL;DR: Elliott holds a meaningful 9.7% stake and 14.8% total economic exposure, signaling sizable activist buying but limited voting control from swaps.

The filing quantifies a direct equity position of 51.13 million shares representing 9.7% of Southwest's 525.19 million shares outstanding and reports approximately $1.344 billion of purchase cost. The additional 26.543 million share equivalent via cash-settled swaps raises economic exposure to 14.8% while the counterparties retain the referenced voting rights. For investors, this is a material ownership disclosure that could presage engagement but does not by itself change governance due to swap mechanics.

Corporate Governance Expert

TL;DR: Elliott's stake is large enough to be influential, yet the swaps explicitly do not grant voting or disposition power.

The Schedule 13D amendment restates purpose as increasing exposure based on belief in the issuer's strategic initiatives. The separation between economic exposure and voting rights is explicit: the Cash Derivative Agreements are cash-settled and Elliott disclaims beneficial ownership of the subject shares. That distinction is central for governance impact: economic alignment is significant, but formal control or proxy influence is limited absent additional agreements or share purchases that carry voting power.

(a)	Title of Class of Securities: Common Stock, par value $1.00 per share
(b)	Name of Issuer: SOUTHWEST AIRLINES CO
(c)	Address of Issuer's Principal Executive Offices: 2702 LOVE FIELD DR, P O BOX 36611, DALLAS, TEXAS , 75235.
Item 1 Comment: The following constitutes Amendment No. 9 ("Amendment No. 9") to the Schedule 13D filed with the Securities and Exchange Commission on August 5, 2024 (as amended, the "Schedule 13D"). This Amendment No. 9 amends and restates Items 3, 5(a)-(c) and 6 and supplements Item 4 as set forth below. Capitalized terms used herein and not otherwise defined in this Amendment No. 9 have the meanings set forth in the Schedule 13D.
Item 3.	Source and Amount of Funds or Other Consideration
	The aggregate cost of the shares of Common Stock directly held by the Elliott Funds is approximately $1,343,906,499. The Reporting Person may effect purchases of the shares of Common Stock through margin accounts maintained for the Elliott Funds with prime brokers, which extend margin credit as and when required to open or carry positions in their margin accounts, subject to applicable federal margin regulations, stock exchange rules and such firms' credit policies. Positions in the shares of Common Stock may be held in margin accounts and may be pledged as collateral security for the repayment of debit balances in such accounts. Since other securities may be held in such margin accounts, it may not be possible to determine the amounts, if any, of margin used to purchase the shares of Common Stock.
Item 4.	Purpose of Transaction
	The Reporting Person increased the Elliott Funds' exposure to the Issuer as a result of its belief that the Issuer's strategic initiatives can position the Issuer to create long-term shareholder value.
Item 5.	Interest in Securities of the Issuer
(a)	See rows (11) and (13) of the cover page to this Schedule 13D for the aggregate number of shares of Common Stock and percentage of shares of Common Stock beneficially owned by the Reporting Person. The aggregate percentage of shares of Common Stock reported beneficially owned by the Reporting Person is based upon 525,187,709 shares of Common Stock outstanding as of July 23, 2025, as disclosed in the Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2025, filed by the Issuer with the Securities and Exchange Commission on July 24, 2025.
(b)	See rows (7) through (10) of the cover page to this Schedule 13D for the shares of Common Stock as to which the Reporting Person has the sole or shared power to vote or direct the vote and sole or shared power to dispose or to direct the disposition.
(c)	The transactions in the shares of Common Stock effected by the Reporting Person during the past sixty (60) days, which were all in the open market, are set forth on Schedule 1 attached hereto and incorporated by reference herein.
Item 6.	Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer
	Item 4 of the Schedule 13D is incorporated herein by reference. The Elliott Funds have entered into notional principal amount derivative agreements (the "Cash Derivative Agreements") in the form of cash settled swaps with respect to an aggregate of 26,543,000 shares of Common Stock of the Issuer (collectively representing economic exposure comparable to 5.1% of the shares of Common Stock of the Issuer). The Cash Derivative Agreements provide the Elliott Funds with economic results that are comparable to the economic results of ownership but do not provide them or EIM with the power to vote or direct the voting or dispose of or direct the disposition of the shares that are referenced in the Cash Derivative Agreements (such shares, the "Subject Shares"). EIM disclaims beneficial ownership in the Subject Shares. The counterparties to the Cash Derivative Agreements are unaffiliated third-party financial institutions. EIM has combined economic exposure in the Issuer of approximately 14.8% of the shares of Common Stock outstanding. Except as set forth herein, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the persons named in Item 2 hereof and between such persons and any person with respect to any securities of the Issuer, including any class of the Issuer's securities used as a reference security, in connection with any of the following: call options, put options, security-based swaps or any other derivative securities, transfer or voting of any of the securities, finder's fees, joint ventures, loan or option arrangements, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.
