I paid for the WiFi and it didn’t work during the whole flight

Impressed that Alaska Air(for our domestic flight) transferred our checked bags to EVA (for our international flights) so that we didn't have to handle them, & we just picked them up at our final destination.

I enjoyed the movie selection. I’m glad I saw ahead of time to bring personal ear buds. I don’t normally have them with me and airlines used to give them out.

man & woman back side flight attendant was very rude. I live in Seattle. I use a lot of time Alaska flights. I always like them for fact that my favorite airline employees very rude. It’s disappointing. .

Great experience, staff and crew were very professional, friendly and helpful!

I think Alaska should start including free meals on these longer trips.

Wheelchair assistance was excellent. I had a saver fare, but was given a seat in Premium. So very nice!! Extra legroom, complimentary beer. The flight crew was very nice and efficient. The gate agent in Seattle double checked to make sure I was able to board the plane all right while using my cane. I boarded first. So considerate! The flight was smooth, and right on time.

There is nothing critical to complain about but I would say the snacks are pretty bad Airline staff could be aggressive the way they move through the aisles and the plane I also got hustled for a small wallet size men bag and force the consolidated with my carry on item we're talking about a wallet size bag.

Departed on time and had an efficient boarding process. The inflight wifi was not working on one of the flights.

How can I review what was denied to me. Instead of offering to let me pay for the ticket I got booted of my flight with no way home and no choice but to purchase another ticket for 12 hours later. Filing a complaint with the DOT
