Southwest Airlines and Singapore Airlines Group announced a partnership to offer travelers single-ticket journeys to and from the US, connecting to places where the carriers fly.

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 US served by Southwest — Los Angeles, Seattle/Tacoma and San Francisco. In those shared gateway airports, said the announcement, international travelers can now seamlessly connect to nearly 120 airports in the Southwest network.

Andrew Watterson, Southwest’s COO, said, “Singapore Airlines becomes the eighth carrier in our partnership portfolio exemplified by its quality and reach.” These carriers, he said, “are facilitating access to our network for a growing global audience drawn to our improved onboard product and increasingly choosing to fly with us.”

With assigned seating, optional Extra Legroom and enhanced boarding all introduced earlier this year, said the announcement, “Southwest continues to invest purposefully in onboard experiences with feedback-driven enhancements toward greater comfort and more choice.”
