Frontier has round-trip flights from Austin (AUS) to Santa Ana, California (SNA) for $67, NONSTOP. $34 each-way. A few Saturday to Wednesday flights in February. Origin/Destination reversible.
Note: This will put you about 21-minutes from Disneyland, or Newport Beach, and about 55-minutes from downtown Los Angeles. We’re highlighting this flight since they are cheaper than LAX flights if you want to do a SAT-WED trip.
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 +$30 each-way. You can avoid paying for seat selection if you accept the randomly assigned seat prior to boarding.
