Southwest Airlines announced that it would add nearly two dozen new flights from Austin beginning next year. Saying it has been the largest carrier serving the Texas capital for at least 30 years, the airline said it plans to increase service on March 10, 2022, by more than 20 flights a day with nonstop service between Austin and nine new and returning destinations, as well as adding additional frequencies on routes already served from the city. In total, Southwest will offer nonstop service between Austin and 46 destinations on up to 105 departures a day. Beginning March 10, 2022, Southwest’s schedule will include daily nonstop service between Austin and these new destinations: Amarillo, Texas; Charleston, S.C.;  Columbus, Ohio (will also operate during peak holiday travel periods in 2021); Midland/Odessa, Texas (previously flown nonstop in 2009); and Ontario, Calif. Dave Harvey, vice president of Southwest Business, said that as the carrier continues to strengthen its network in Austin, customers will see more flights on key routes as well as new destinations across the airline’s map. Southwest began serving Austin on Sept. 15, 1977.
