Southwest Airlines is set to embark on its first international airline partnership next month, expanding its list of international gateways to include Denver and Nashville. This development follows the announcement of Baltimore as the initial gateway, paving the way for an interline agreement with Icelandair. The agreement was formalized at a ceremony in Washington.

The partnership will allow Southwest's Rapid Rewards members to redeem points on flights to Iceland and Europe. "Interline partnerships are very common in the airline industry. But it's our first one, so it's very exciting for us," said Andrew Watterson, Southwest's chief operating officer.

Initially, travelers can book itineraries with seamless connections between the two carriers via Icelandair's website starting February. The focus will be on Baltimore/Washington International Thurgood Marshall Airport as the U.S. gateway.

Ryan Green, overseeing Southwest's changes announced last year, stated that expansion plans include Denver International Airport and Nashville International Airport. Deeper integration is expected in 2026 when Southwest introduces assigned seating.

The ceremonial launch included gift exchanges and a toast with Brennivin, Iceland's national drink. "This will be a wonderful partnership," said Svanhildur Hólm Valsdóttir, Iceland's ambassador to the U.S.

Southwest aims to announce another international partner in 2025 as part of efforts to offer more destinations through Rapid Rewards. "We're having conversations with both additional transatlantic carriers as well as transpacific carriers," Green mentioned.

In recent years, Southwest has invested significantly in modernizing its technical infrastructure to facilitate such global partnerships and other enhancements like redeye flights.

"This is a new capability we have. And that's what transformation is all about," Watterson noted regarding future expansions.
