SAN DIEGO (FOX 5/KUSI) — Budget airline Frontier has announced new nonstop routes coming to San Diego International Airport later this year. Beginning in mid-June, the airline will have regular service flights to and from Chicago O-Hare International Airport, Bergstrom International Airport in Austin, Texas, and Salt Lake City International in Utah. With these new routes, which were announced by the carrier on Tuesday, Frontier will have nonstop offerings to eight destinations through San Diego. Alaska Airlines now offers nonstop service between San Diego, Washington, DC “With Frontier’s trademark low fares available on eight nonstop routes from SAN, now is a better time than ever for consumers in Southern California to make Frontier their airline of choice,” Josh Flyr, vice president of network and operations design for Frontier Airlines, said in a release. The Chicago O'Hare service will be the first new route to launch, starting daily trips on June 12. Trips to Salt Lake City and Austin will begin the following day, June 13, and continue three times a week and four times a week, respectively. To commemorate the new routes, Frontier is offering extra discounted tickets for passengers for trips to each of the cities through Aug. 18. The peak travel period around the Fourth of July holiday is excluded from the promotion. The introductory fare will start at $39 for Salt Lake City, $59 for Austin and $69 for Chicago, according to the airline.
