Southwest Airlines has secured a new partnership with Turkish Airlines, which is scheduled to begin in January 2026.
The partnership will offer travellers single-ticket, transatlantic journeys between the US and Istanbul, unlocking onward connections across both carriers' networks.
Turkish Airlines flies to more than 350 destinations in 132 countries from its global hub, Istanbul Airport, including ten airports in the US served by Southwest.
Tickets will be available to passengers for these partnership routes next year through Turkish Airlines, travel agents, and travel websites.
“We're grateful for this new relationship that will usher in thousands of international travellers each week through experiences that showcase the best of both carriers and globally enhance awareness of the Southwest brand,” said Southwest Airlines chief operating officer Andrew Watterson.
The announcement builds on Southwest's existing partnerships with other international carriers, including Icelandair, China Airlines, EVA Air, Philippine Airlines, and Condor Airlines.
