Southwest Airlines Co (NYSE: LUV) is a domestic passenger airline company that operates scheduled air transportation for passengers across the United States and select international destinations. Revenue is generated primarily through passenger ticket sales, with ancillary income from baggage fees (introduced in 2025, ending the long-standing Bags Fly Free policy), extra legroom seat upsells, and co-branded credit card and loyalty arrangements through its Rapid Rewards frequent flyer program. In January 2026, Southwest began operating assigned seating across a retrofitted fleet of 780 aircraft, a structural product shift designed to capture upsell revenue and attract business travelers. The airline expanded distribution in 2025 to include Google Flights, Kayak, Skyscanner, Expedia, and Priceline, and launched an in-house vacation bundling product called Getaways. Southwest also entered international interline partnerships allowing partner airlines to sell tickets on Southwest segments. As of the 10-K filed February 5, 2026, the company was executing a broad transformation involving network expansion, cabin redesign with new RECARO seats, faster WiFi, and in-seat power.

Passenger ticket sales are the primary revenue source, supplemented by ancillary fees including checked baggage charges (introduced 2025), extra legroom seat premiums, and Rapid Rewards loyalty program revenue.
