MiraFlew with Alaska AirlinesAug 2024
we stayed at crowne Plaza at SeaTac. super convenient to Link.
DanielleFlew with Alaska AirlinesJul 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.

Instant upgrade to First Class based on my One World status. Better than AA.

Instant upgrade to First Class based on my One World status. Better than AA.

I had to cancel my flight for health reasons. They gave 0 options to get my money back or credit me another flight. Makes no sense, but they are greedy

no entertainment which was ok with us. Great crew, great ascent, rockier landing, empty air lane so very comfortable. fun pilot

I feel that for the price that I paid, I should’ve received zone one boarding. Said I was zone two. And even though I paid for an upgraded seat, I was lucky to get a space for my carry-on baggage. So I think the value wasn’t there.

Did not have food. There was no entertainment. Flight was great, on time, crew was excellent

The fly was delayed but otherwise, not bad. I was in First class so not too much to complain. The SEA airport though is a different story.

Cheerful crew, arrived early, but did have to wait for a gate because of that. But it was a pleasant flight.

Inbound plane was delayed so we left later (20-30 mins). There was no screen in the plane. Flight was smooth, pilot was extra communicative as we had to wait during taxi and upon arrival also. Staff was great

It was good for lax to sea even tho it was delayed by an hour. That is not this crews fault however.

Everything went smoothly at the airport and on the flight. So, I had a positive experience with no issues.
