Round trip
San Diego from San Antonio just hit $136 round trip on Frontier, tying the lowest price we have ever tracked on this route and landing 55% below the roughly $300 it usually costs. With one easy connection, it is a great low-cost pairing for a beach and craft-beer weekend in San Diego this fall or winter. Fares at the all-time floor like this rarely stick around.
