Southwest Airlines Co. (NYSE: LUV) is launching its first-ever airport lounge network in partnership with Chase, a strategic move to monetize its Rapid Rewards loyalty program and compete for high-margin premium traveler spend.

Construction has begun on four initial lounges at Austin, Baltimore, Honolulu and Nashville airports, with openings expected in late 2027. Southwest plans at least seven additional lounges across its system in subsequent years, targeting high-demand business and leisure markets.

Access will be granted through a new premium Southwest Rapid Rewards Credit Card, to be issued by Chase and launched in 2027. This deepens Southwest's 30-year partnership with Chase and taps a revenue stream the airline has historically left on the table—most carriers derive substantial annual revenue from co-branded card fees and annual membership spend.

Tony Roach, Executive Vice President and Chief Customer Brand Officer at Southwest, said the lounges represent "a natural extension of the airline's authentic hospitality" and a strategic investment in the Rapid Rewards program.

Why this matters: Southwest has lagged peers in premium ancillary revenue. American, Delta and United each generate billions annually from credit card partnerships, premium cabin sales and lounge networks. LUV's 2025 capacity for 134 million customers across 120 airports provides a large addressable base for upgrade conversion. The late 2027 timeline is material—expect credit card partnership revenue disclosures in 2026 guidance and lounge-related EBITDA contributions to flow through starting 2028. Watch for card partnership terms (annual fees, sign-up bonuses, revenue share) when disclosed; competitors' premium cards command $450-$695 annually, a margin-accretive revenue pool Southwest has underexploited.
