Even Bigger Where Southwest Airlines® is Biggest

Southwest® is boosting year-over-year frequencies on eight routes in Las Vegas – where Southwest offers nonstop service to 22 of the top 25 U.S. travel markets² – while launching international service there for the first time. The routes with varying increases are Nashville, Tennessee; Burbank, California; Indianapolis; Kansas City, Missouri; Orlando, Florida; New Orleans; Reno, Nevada, and Tampa, Florida. Additionally, the only nonstop between Las Vegas and Cancun is scheduled to begin June 4, 2026, along with new flights connecting Vegas with Los Cabos, Mexico, and Puerto Vallarta, Mexico.

Southwest’s largest Florida operation in Orlando is growing year-over-year frequencies on 11 routes, enhancing the airline’s existing service to 63 unique destinations³. Orlando increases include Austin, Texas; Nashville, Tennessee; Baltimore; Indianapolis; Las Vegas; Kansas City, Missouri; Milwaukee; New Orleans; Pittsburgh; Louisville, Kentucky; and San Juan, Puerto Rico.

With the new Terminal 1 at San Diego International Airport open for business, Southwest is scheduled to offer an all-time high of 134 trips on peak days and an all-time high of 43 destinations from America’s Finest City³. A new route is set to launch June 4, 2026, between San Diego and Boston, while the San Diego-San Francisco route grows to eight departures on peak days.

The carrier’s offerings in the Texas state capital continue to grow in summer 2026 with a new daily route between Austin and Cincinnati and the return of seasonal service to and from Seattle. Added breadth in frequencies between Austin and Indianapolis (three flights daily), as well as Austin and San Francisco (two flights Monday through Friday), builds on Southwest’s 48-year history at Austin Bergstrom International Airport.

Shining in the Golden State

Southwest is increasing its best-in-industry⁴ intra-California service with a redesigned schedule at Los Angeles International Airport. Service between LAX and the following cities is increased on peak days: Sacramento (from five flights to six), San Francisco (from four flights to six), and San Jose (from six flights to seven). This new service complements the San Diego-San Francisco growth, as well as the recent return to the Southwest network of Burbank-San Francisco.

The midnight sun rises on Southwest
