Southwest launches Knoxville summer route

Southwest Airlines started flying from Knoxville’s McGhee Tyson Airport on March 5, 2026, ending a long campaign to bring the carrier to East Tennessee. (swamedia.com) (wate.com) The initial launch brought twice-daily service between Knoxville and Nashville, plus daily roundtrip flights to Baltimore, Dallas Love Field and Orlando. Southwest put those first five daily round-trips on sale when it announced Knoxville service on August 14, 2025. (swamedia.com) The spring schedule also added seasonal Denver service on Saturdays and Sundays in April 2026. On October 9, 2025, Southwest said Knoxville would get another summer addition: nonstop Tampa flights and daily Denver service starting in June 2026. (wate.com) (wbir.com) That gives Southwest six destinations from Knoxville in summer 2026: Nashville, Baltimore, Dallas, Orlando, Denver and Tampa. Knoxville became Southwest’s third airport in Tennessee, joining Nashville and Memphis. (wbir.com) (swamedia.com) Local officials tied the launch to both tourism and business travel. Southwest Chief Executive Bob Jordan said the Knoxville opening was part of the airline’s broader route-map growth, while Tennessee Governor Bill Lee called the state a “top global travel destination and business hub.” (swamedia.com) The airport has been growing fast before Southwest’s arrival. McGhee Tyson handled about 3.3 million passengers in 2024, and local station WATE reported the airport was pursuing roughly $700 million in upgrades, including a new parking garage with about 3,600 spaces, more gates and expanded security checkpoints. (wate.com) Southwest’s Knoxville entry also lines up with a wider summer 2026 network push. In that October 2025 schedule release, the airline said it was increasing service in major markets including Orlando, Las Vegas and San Diego while publishing more summer flying across the system. (southwestairlinesinvestorrelations.com) For Knoxville travelers, the practical change is simple: Southwest is no longer a future promise at McGhee Tyson. It is now flying, and by June 2026 its local map is scheduled to be larger than the one unveiled at launch. (wate.com) (wbir.com)
