American Airlines has round-trip flights from Austin (AUS) to San Francisco (SFO) for $134 with a connection. $67 each-way. Flights January to November. Weekends available. Origin/Destination reversible. Holiday Blackouts apply.
Note: This deal has lots of (FRI-SUN/MON) weekend availability, but it requires a stop. A fair trade in our opinion. Monday returns have better flight times.
Note: Carry-on bag is allowed for free, but seat selection has a fee. Upgrades into “Regular Economy” are available for +$30 each-way. You can avoid paying seat fees with the American Airlines credit-card perk, or by not selecting a seat and being randomly assigned your seat at the gate.
