Cheap SEA to SFO Flights

Only 1 of the party of 4 was able to take the flight. Unfortunately, my son, his roommate and fiancé were not able to go do to health concerns and coronavirus. However, Alaskan airlines stepped up and issued flight vouchers for the cancelled flight. I can’t thank you enough. The tickets were booked through Expedia, but your agent handled every. Very impressive, great customer service.

I paid extra for extra leg room on flight from LAX to SEA. I still did not have enough legroom and neither did the woman next to me. We wondered how bad the other seats were.

Gate agent in Seattle was very friendly, and upbeat.
