American Airlines has round-trip flights from Austin (AUS) to San Francisco (SFO) for $134 with a connection. $67 each-way. August to November. Weekends available in August and September. Origin/Destination reversible.
Note: We often see United offer fares for a similar price, but we often ignore them because they charge a $60 fee for carry-on bags and usually have limited weekend availability.
Note: Carry-on bag is allowed for free, but seat selection has a fee. You can avoid paying seat fees by not selecting a seat and being randomly assigned your seat at the gate.
