RIO DE JANEIRO, June 8, 2026 /PRNewswire/ — Southwest Airlines Co. (NYSE: LUV) and Singapore Airlines (SIA) have partnered to offer travelers around the globe single-ticket journeys to and from the United States, connecting to places where Southwest and Singapore Airlines fly. Southwest Executives shared the news of the interline partnership during the International Air Transport Association (IATA) Annual General Meeting in Brazil.
The SIA Group, which includes Singapore Airlines and Scoot, operates service to more than 130 destinations in 35 countries and territories, and flies between its global hub, Singapore Changi Airport and three airports in the United States served by Southwest—Los Angeles (LAX), Seattle/Tacoma (SEA), and San Francisco (SFO). In those shared gateway airports, international travelers can now seamlessly connect to nearly 120 airports in the Southwest network. Tickets are available through Singapore Airlines, travel agents, and travel websites.
“Singapore Airlines becomes the eighth carrier in our partnership portfolio exemplified by its quality and reach. 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,” said Andrew Watterson, Southwest Airlines Chief Operating Officer. “Journeys that pair Southwest and Singapore Airlines not only connect new geographies but also create consistent high-quality Customer experiences.”
With assigned seating, optional Extra Legroom1 and enhanced boarding all introduced earlier this year, Southwest continues to invest purposefully in onboard experiences with feedback-driven enhancements toward greater comfort and more choice. These thoughtful improvements aim to showcase Hospitality for which the People of Southwest Airlines are world famous.
Southwest Airlines has initiated service at five airports in 2026 including St. Thomas, in the U.S. Virgin Islands, Sint Maarten, Santa Rosa/Sonoma County, Calif., Knoxville, Tenn., and Anchorage.
Including Singapore Airlines, Southwest now has eight active partnerships with overseas carriers connecting travel between its network and places across the globe in Asia, Europe, the Middle East, and Africa.
