Southwest Expands International Routes and Loyalty Partnerships for 2027

Southwest Airlines is expanding its international reach through 11 new nonstop routes scheduled to begin between November 2026 and June 2027, alongside a loyalty partnership with Etihad Airways planned for spring 2027. The initiatives will broaden travel options across the United States, Mexico, Central America, the Caribbean, and Etihad's global network, according to reports published by Simple Flying and Aviacionline.

The loyalty agreement, announced on October 16, 2026, will connect Southwest's Rapid Rewards program with Etihad Guest. Eligible members of both programs will be able to earn and redeem rewards on flights operated by either airline, giving Southwest customers access to additional international destinations and Etihad members more options across the Americas.

Mark Potter, Managing Director of Etihad Guest, described the agreement as an addition to the airline's existing loyalty partnerships and its North American presence.

"We're delighted to announce our partnership with Southwest Airlines and Rapid Rewards, an exciting addition to our growing portfolio of loyalty partners and Etihad's presence across North America," Potter said.

Potter also said the arrangement would expand destination choices for Etihad Guest members while introducing Rapid Rewards members to Etihad's international network, which includes destinations such as Krabi, Zanzibar, and Hanoi.

Southwest Vice President of Rapid Rewards Nandika Suri said the agreement would expand opportunities for members to use their points across international destinations.

"Our international loyalty partnership with Etihad Guest will give Rapid Rewards members even more value from their membership and create exciting opportunities to earn and redeem points across Etihad's global network beginning in Spring 2027," Suri said.

The partnership forms part of Southwest's broader Rapid Rewards changes announced in October 2026. The airline plans to introduce Silver, Gold, and Platinum status tiers starting January 1, 2027, and expand international reward redemptions through partnerships with Etihad, Icelandair, and China Airlines in spring 2027.

In a separate statement, Potter emphasized the broader travel opportunities created by connecting the two programs.

"We are pleased to announce our partnership with Southwest Airlines and Rapid Rewards, a valuable addition to our growing portfolio of loyalty partners and to Etihad's presence in North America," Potter said.

He added that the programs would offer members more flexibility when planning trips across their combined networks.

"brings together two programs with a common goal: rewarding loyalty and giving members a wider variety of options for their travels," Potter said.

Suri also highlighted the potential for members to access more destinations through the agreement.

"will give Rapid Rewards members even more value for their membership," Suri said.

The partnership will allow travelers to connect with destinations served by both airlines, although detailed redemption rules and availability arrangements have not yet been published.

Suri also welcomed the prospect of extending the airline's international rewards options.

"connect our members with more destinations and rewarding travel experiences, while welcoming Etihad Guest members to enjoy the Southwest Airlines network," Suri said.

Separately, Southwest's 11 planned international routes will strengthen service from Nashville, Austin, Las Vegas, Columbus, and Pittsburgh. Four routes from Nashville will serve Liberia, Aruba, Nassau, and Providenciales, while Austin will gain flights to San José, Liberia, Punta Cana, and Nassau.

The remaining routes include Las Vegas to Puerto Vallarta, Columbus to Punta Cana, and Pittsburgh to Punta Cana. The Las Vegas service is scheduled to start November 1, 2026, while the other services begin between February and June 2027, according to Cirium data cited by Simple Flying.

Southwest is also adjusting its domestic network around short connecting flights. Cirium Diio data cited by Simple Flying identifies Denver to Colorado Springs as the airline's shortest route at 63 nautical miles, or 117 kilometers, with three daily flights listed for October 2026.

U.S. Department of Transportation data cited in the same report shows that 96% of passengers on the Denver-to-Colorado Springs route connect to another flight in Denver. Southwest's wider network strategy combines these short feeder services with new international routes and expanded loyalty options.
