$199 - Roundtrip Direct Flights to Austin from San Francisco
Alaska Airlines is offering roundtrip direct flights to Austin from San Francisco for $199 including all taxes and fees.
This is one of the best deals I’ve ever found on flights to Austin.
The cheapest flights fly out on Tuesdays, Wednesdays, or Saturdays, with flights back a couple of days later.
If you want to pick your travel dates more strictly, you should still be able to find direct flights for under $300, either with Alaska Airlines, American, Continental, Delta, or Frontier.
Alaska Airlines still offers the cheapest though for direct flights at a cost of $221 for roundtrip flights -> Friday through Monday.
