Frontier has round-trip flights from San Antonio (SAT) to Ontario, California (ONT) for $97, NONSTOP $49 each-way. Flights from late-July to November. Weekends available until mid-August. Origin/Destination reversible.
Note: Ontario is 1-hour away from downtown Los Angeles and is also accessible via [Ontario Metrolink] station for about $11.
Note: Frontier fares do not include a free carry-on bag. Only a small personal item (like a Jansport City Scout backpack) is free. Checked bags cost +$35 each-way. You can avoid paying for seat selection if you accept the randomly assigned seat prior to boarding.
Note: I’m currently using the [Jansport Right Pack] as my “personal item” when I fly Frontier. Which is slightly more than expensive than the [Jansport City Scout] because its fabric is Cordura instead of Polyester. Both have the same dimensions which are: 18″ x 13″ x 8.5″. There is half-an-inch of extra depth than what is officially allowed by Frontier, but it has never been a problem for me. The bag has a large main compartment, which makes it ideal for stuffing as much as you can into the limited amount of space.
