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.
