AUSTIN (KXAN) — Frontier Airlines announced Tuesday it will begin nonstop service between Austin and San Diego in June. Flights will operate four times a week beginning June 13. The airline anticipates operating the new route year-round. AUS Data Hub: Passenger totals, busiest months an d new flights in 2025 "We are thrilled to announce another new route as we continue to grow our presence in Austin," said Josh Flyr, Frontier's vice president of network and operations design. "With Frontier’s trademark low fares available on 11 nonstop routes from AUS, now is a better time than ever for consumers in Central Texas to make Frontier their airline of choice." Alaska Airlines and Southwest Airlines currently both serve the AUS-SAN route. San Diego will be Frontier's seventh new route from AUS this year. Service to Chicago O'Hare, Cincinnati, Orlando and Phoenix began earlier this month, while flights to Miami and Philadelphia are set to take off May 22. In 2024, Frontier more than doubled its passenger total at AUS from the previous year, carrying almost 225,000 passengers in and out of Austin. The total was the highest since the beginning of the COVID-19 pandemic, but still only about a quarter of the number seen in 2019. Last year, 1.03% of passengers at AUS flew on a Frontier flight, up from 0.46% in 2023, but down from 5.12% in 2019. ...read more read less
