Southwest this week signed an interline agreement with Singapore Airlines, opening the door to single-ticket flights via three U.S. West Coast gateways.
Interline deals allow customers of partnered airlines to book connecting flights on a single itinerary, opening up the networks of both carriers through designated gateway airports. Bags are checked through to the final destination, meaning travelers do not need to collect and recheck them during their layover.
Southwest officials said customers will be able to book connecting flights with Singapore Airlines from Los Angeles, Seattle, and San Francisco. Singapore Airlines serves all three cities from Changi Airport in Singapore.
Tickets for connecting flights are now available for purchase.
“Singapore Airlines becomes the eighth carrier in our partnership portfolio exemplified by its quality and reach,” Southwest COO Andrew Watterson said in a news release. “These carriers are facilitating access to our network for a growing global audience drawn to our improved onboard product and increasingly choosing to fly with us.”
Southwest’s other interline partners are All Nippon Airways, China Airlines, Condor, EVA Air, Icelandair, Philippine Airlines, and Turkish Airlines.
