United, Delta, and Alaska Airlines have round-trip flights from Austin (AUS) to Los Angeles (LAX) for $124-$133, NONSTOP. Flights in May, August, September, October, November, December, January, February, and March. Weekends available. Origin/Destination reversible.
Carry-on bag and personal item are allowed without additional fee on Delta and Alaska Airlines.
United’s “Basic Economy” fares do not allow for a free carry-on bag. Only a personal item (like a small laptop bag) is free. Seats are randomly assigned for free prior to boarding. If you have the United Explorer credit-card, use the “free checked bag” perk.
The personal item size on United is smaller (9 x 10 x 17 inches) than Frontier or Spirit (8 x 13 x 18 inches).
