Southwest Adds New City, 17 Routes

Southwest is shaking up its network with service to a brand-new destination and over a dozen additional routes. The Dallas-based airline has announced new destinations in recent weeks, including St. Thomas.

Starting next year, Knoxville, Tennessee, will join Southwest’s network. Flights are slated to begin on March 5.

From Knoxville, the carrier plans to serve Nashville twice per day, along with daily flights to Baltimore, Dallas, and Orlando, Florida.

By the end of this month, the airline says it will announce another destination “where the ocean wears two shades of blue and every landing feels like an adventure. More adventures also await at one of Southwest’s homes on the Pacific Coast next year.”

Other Routes

In addition to its new destinations, Southwest will bolster service in other markets.

From San Diego, it will add daily, year-round service to Eugene, Oregon; Maui, Hawaii; Portland, Oregon; Puerto Vallarta, Mexico; and Seattle. Flights are scheduled to start on March 7.

The carrier will also add Saturday-only flights from San Diego to Bozeman, Montana, and Spokane, Washington.

The carrier will add a batch of new and returning routes beginning on March 5. Southwest is introducing twice-daily service on three routes: Chicago Midway and Milwaukee; Phoenix and Tucson, Arizona; and Little Rock, Arkansas, and Nashville.

In addition, the airline will operate twice-daily flights between Chicago Midway and Des Moines, Iowa; Tulsa, Oklahoma; and Wichita, Kansas, starting on March 5, along with twice-daily flights between Dallas and Oklahoma City.
