SOUTHWEST AIRLINES UNVEILS ITS “SOUTHWEST. EVEN BETTER.” TRANSFORMATIONAL PLAN AT INVESTOR DAY • Reimagines core product to meet evolving Customer preferences and increase revenue opportunities • Launches new commercial initiatives to enhance Customer Experience and drive value while preserving flexible policies like bags fly free1 • Expects to deliver in 2027: approximately $4 billion2 in cumulative incremental earnings before interest and taxes (EBIT) contribution and after-tax return on invested capital (ROIC) of 15 percent or greater, well above weighted average cost of capital (WACC) • Board approves $2.5 billion share repurchase program DALLAS—Sept. 26, 2024—Southwest Airlines Co. (NYSE: LUV) (“Southwest®” or the “Company”) today will host an Investor Day briefing in Dallas where Southwest Leaders will outline next steps in a comprehensive three-year plan that builds upon the Company’s unique business model for an even better Southwest. The carrier is transforming its Customer Experience to provide more choices and greater comfort for Customers, designed to drive revenue growth and return the carrier to industry-leading profitability. “We’re now ushering in a new era at Southwest, moving swiftly and deliberately to transform the Company by elevating the Customer Experience, improving financial performance, and driving sustainable Shareholder value,” said Bob Jordan, President, Chief Executive Officer, and Vice Chairman of the Board. Key themes and new initiatives to be detailed at Investor Day include: Transforming Our Product to Meet Customer Preferences Southwest’s transformation is guided by data-driven research of travelers’ changing needs and expectations. Southwest’s evolution will provide even more choices for its Customers and preserve aspects of the business that make the airline unique among its competitors: • Assigned Seating: Southwest will broaden its consumer appeal and boost demand through an assigned seating model. Airline passengers now have a clear preference for seat assignments: 80 percent of Southwest Customers and 86 percent of passengers who choose other airlines want assigned seats. Southwest flies farther than ever, and seat assignments are a higher priority on long-haul flights. The Company expects to

2 begin selling assigned seats in the second half of 2025, with its first flights operating with the new model in the first half of 2026. • Premium Seating: Market research shows that the preference for an assigned seat with extra legroom offers broad appeal for both business and leisure travelers. Southwest will offer extra legroom options with up to five additional inches of pitch for approximately a third of its seats while maintaining a standard economy seat pitch among the best in the industry. New seating product options will drive demand and are expected to generate more revenue per passenger. • Southwest Boarding with Upgrades: Southwest will evolve its boarding process with seat assignments while focusing on operational efficiency and improving the Customer Experience. The updated boarding process will maintain Southwest’s unique and popular approach in boarding through position numbers and signage displayed on stanchions within the gate area. The carrier’s most loyal Customers and those who purchase premium seating will continue to be among the first to board. • Bags Continue to Fly Free: Extensive research reinforces Southwest’s bags fly free® policy1 remains the most important feature by far in setting Southwest apart from other airlines. Based on Southwest’s research, the Company believes that any change in the current policy that provides every Customer two free checked bags1 would drive down demand and far outweigh any revenue gains created by imposing and collecting bag fees. “We’ve spent the past few years laying a foundation that serves as the base of our transformation,” said Ryan Green, Executive Vice President Commercial Transformation. “We’ve already started rolling out modernized cabins with improved WiFi, in-seat power, larger overhead bins, enhanced operational efficiencies, and optimized flight schedules. We will continue to build upon our unique competitive advantages, while adapting to consumer priorities in today’s dynamic environment.” New Offerings to Broaden Appeal and Strengthen Revenue In addition to offering more Customer choice, Southwest will launch new capabilities and products designed to add value and revenue potential: • Global Airline Partnerships: Southwest is formalizing partnerships with international carriers to expand its network and connect Customers with more global destinations to generate additional demand for travel across the Southwest network. Icelandair will

3 become Southwest’s initial partner with an expected launch in 2025 through Baltimore- Washington International Airport, which will serve as its first U.S. gateway for the carriers. The Icelandair partnership will expand gateways throughout 2025, and Southwest intends to add at least one additional partner carrier next year. • Getaways by Southwest: In 2025, the Company intends to launch a new product, Getaways by Southwest, offering vacation packages that are unique to the industry and come with friendly policies that Customers expect from a Southwest-operated venture. These customizable vacation bundles will feature Southwest’s generous cancellation policy and flexibility with its no change fees for flights extending to hotels and other elements of packaged vacations. • Rapid Rewards®3 Enhancements: Throughout the transformation, all Members will earn and redeem points at the same rate that they do today, and Southwest will continue to offer no blackout dates, uncapped reward seat availability, and points that don’t expire. The airline will update its Tier Benefits with the transformation giving A-List and A-List Preferred Members even better benefits. The airline also soon will share updates to its credit card program, including how assigned seats and premium seating will offer Cardmembers even more value. Until then, Cardmembers will continue to take advantage of their current card benefits. Eventually, Rapid Rewards Members also will have more opportunities to earn and redeem points for longer-haul international destinations with development of its airline partnerships and the evolution of its Getaways by Southwest product. Optimizing Operational Efficiencies Southwest is focusing on operational efficiencies to mitigate cost pressures and modernize processes. These efforts are designed to fund nearly all new capacity growth over the next three years without incremental aircraft capital deployment: • 24-Hour Operations: In February 2025, Southwest expects to begin offering redeye flying in key markets to maximize aircraft utilization. • Turn Times Between Flights: The airline is aiming to further reduce the time it takes to turn an aircraft, which is intended to increase its aircraft productivity, while making day- to-day processes easier for Employees.

4 Delivering a Financial Plan to Drive Sustainable Profitability and Shareholder Returns “The strategic vision announced today is designed to return us to financial prosperity and drive value creation,” said Tammy Romo, Executive Vice President and Chief Financial Officer. “We have a clear and measurable path that we expect will enable us to cover our WACC in 2026 and achieve after-tax ROIC of at least 15 percent in 2027.” Key elements of Southwest’s financial plan include: • Cost Discipline: The Company’s multi-year plan is expected to deliver an estimated $500 million run rate of cost savings in 2027, by minimizing hiring, optimizing scheduling efficiency, capitalizing on supply chain opportunities, and improving corporate efficiency. • Strategic Fleet Management: Southwest is pursuing opportunities to monetize the value of its fleet order book and drive a significant fleet modernization, with the goal of achieving an average fleet age of just five years in 2031. The Company’s fleet strategy is expected to reduce average aircraft capital expenditures to approximately $500 million through 2027. • Prudent Capital Deployment: Southwest is balancing its capital allocation priorities to minimize capital expenditures on aircraft, continue investing in infrastructure that optimizes operations, and manage debt to preserve the airline’s investment-grade balance sheet, all while returning capital to Shareholders through dividends and share repurchases. The Board of Directors today approved a $2.5 billion share repurchase program, reflecting the Board’s confidence in the strategic plan and new revenue- generating initiatives, and in management’s ability to execute. Financial Targets The Company’s three-year financial plan is expected to support its long-term targets for sustainable profitability: • Approximately $4 billion2 in cumulative incremental run rate EBIT contribution in 2027 • ROIC of 15 percent or greater, well above WACC in 2027
