Southwest, Singapore Airlines Sign Interline Agreement

‍RIO DE JANEIRO — Southwest Airlines (WN) announced an interline partnership with Singapore Airlines (SQ) at the International Air Transport Association (IATA) Annual General Meeting in Brazil. The agreement allows travelers to book a single ticket on both carriers and seamlessly check their bags through to their final destination.

Singapore Airlines operates to more than 130 destinations in 35 countries, allowing WN passengers to expand their reach far beyond the United States. Similarly, SQ passengers can now access WN’s domestic network with nearly 120 destinations. The two carriers overlap at Los Angeles (LAX), San Francisco (SFO), and Seattle (SEA).

There are no deals for reciprocal loyalty program benefits, as the partnership is only a simple interline agreement.

Southwest has been steadily growing its international partners, and SQ marks the carrier’s eighth. The airline also has interline agreements with Icelandair, China Airlines, Eva Air, Philippine Airlines, Condor Airlines, Turkish Airlines, and All Nippon Airways.

Comments from Southwest COO

"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."

The carrier has specifically noted that it is looking to expand its global reach, and travelers can continue to expect new announcements.
