Southwest’s Summer 2026 Schedule Plans Eight Routes

Southwest has opened its summer 2026 schedule, unveiling a broad expansion of its route network that includes new service, added frequencies, and the airline’s first flights to Alaska.

Among the highlights, Southwest will begin its previously announced service to Anchorage on May 15, 2026, connecting the Alaska hub with Denver and Las Vegas. Anchorage will become the 122nd airport in the carrier’s network.

The airline also plans major growth across several airports. In Las Vegas, Southwest will add international service to Cancun beginning June 4, along with new flights to Los Cabos and Puerto Vallarta.

Frequencies to a number of domestic destinations — including Nashville, Tennessee; Burbank, California; Indianapolis; Kansas City, Missouri; Orlando, Florida; New Orleans; Reno, Nevada; and Tampa, Florida — will increase year over year.

In Orlando, Southwest will bolster its position by adding more flights to 11 cities, including Austin, Texas; Baltimore, Maryland; Kansas City; Las Vegas; Nashville; Milwaukee, Wisconsin; New Orleans; Pittsburgh; Louisville, Kentucky; and San Juan, Puerto Rico.

West Coast Growth

In San Diego, the opening of the new Terminal 1 will enable the airline to operate a record high of 134 peak-day departures to 43 destinations, it said.

A new nonstop route between San Diego and Boston begins June 4, and San Diego–San Francisco flights will increase to eight daily frequencies on peak days.

In the LA Basin, the airline will boost Los Angeles service to Sacramento, San Francisco, and San Jose while restoring Burbank–San Francisco flights.

In Austin, Southwest will launch new daily service to Cincinnati and resume seasonal flights to Seattle. The carrier also plans to increase Austin–Indianapolis service to three daily frequencies and Austin–San Francisco to two weekday flights, going head-to-head with Delta in the Texas capital city.
