Good Ol’ rocky top

Southwest Airlines® is scheduled to introduce twice-daily service between Knoxville and Nashville, as well as daily roundtrip flights between Knoxville and Baltimore, Dallas, and Orlando, Florida. 

Southwest, the Official Airline of the Southeastern Conference, is looking forward to taking sports fans to and from events in Knoxville and connecting Customers to the gateway to the Great Smoky Mountains. 

Knoxville joins St. Thomas, United States Virgin Islands, as the second new destination Southwest® has announced this summer. By the end of August, the airline intends to 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. 

Taking off at the new T1 in San Diego 

Southwest is California’s largest carrier in terms of daily departures, available seats, and Customers boarded¹ and is continuing to increase its service in the Golden State with the new Terminal 1 opening next month at San Diego International Airport. Daily, year-round service is set to begin March 5, 2026, between America’s Finest City and Eugene, Oregon; Maui, Hawaii; Portland, Oregon; Puerto Vallarta, Mexico; and Seattle. 

Southwest is also growing its Spring Break ski destinations with Saturday service slated for March 7, 2026, connecting San Diego with Bozeman, Montana, and Spokane, Washington. The two new routes complement existing service to popular winter recreation areas near Albuquerque, New Mexico; Boise, Idaho; Denver; Reno, Nevada; and Salt Lake City.  

Networking is everything
