Alaska Airlines has round-trip flights from Austin (AUS) to Seattle (SEA) for $177-$197, NONSTOP. Flights in August. Very few weekends available.
Some small OTAs on Skyscanner have this for as low as $177; which is cheaper than the airline. If you plan on booking there, beware of any site that charges a fee to cancel a ticket within the 24-hour “free” period. Use unknown booking sites at your own risk.
Allows one carry-on bag and one personal item for free. You can avoid paying for seat selection by accepting the randomly assigned seat at the gate.
