MiraFlew with Alaska AirlinesSFO-SEAAug 2024
we stayed at crowne Plaza at SeaTac. super convenient to Link.
Verified travelerFlew with Alaska AirlinesSFO-SEAJul 2024
It is a very crowded flight, so I advice to choose seats in advance. We didn’t have that option and that was the only complaint I’d have because they put us in the middle seats and we both wanted aisle seats. My sister was able to switch but I wasn’t. She was switched to the back, almost to the last row.
