They were really helpful with every question and my kids had never been on a plane and the staff made them feel comfortable

Very expensive for short flights. Can’t communicate with Alaska Air about passport issue at check-in. Also no replies to my text messages. Wanted to extend our vacation for two more days but this expensive flight ticket is called SAVER and I couldn’t make changes or cancel or get a credit even, so I paid another airline for the return trip. Extremely disappointed.

There was no seating at the gate, no where to charge your devices, super crowded. Boarding in group F meant all luggage space was taken when it was time for me to board. The boarding crew was short with everyone and seemed irritated. The luggage space was insufficient, the seat was too small for me (6'4") and very uncomfortable trip. I was in a middle seat between a person snoring the whole trip and a person with very strong body odor. The flight crew was terse and unfriendly, seemed irritated and impatient. Yelled a lot at people with earbuds in, understandable. Finally, we arrived 10 minutes early, only to sit on the tarmac for 20 minutes and wait for a gate. Worst flight experience I've had in years.

My seat was comfortable. There was no TV on the airplane.

Flight kept getting delayed. Multiple children forced to stay awake for a flight that took longer than expected.

Flight was delayed because overhead bin didn’t close. The most insanely stupid thing I’ve ever heard.

The steward on my flight went above and beyond in hospitality. So friendly and helpful. If I could give him more stars I would. I was so impressed I plan to use Alaska whenever possible and will praise highly to family and friends. (Ive already told my daughter and I’n-laws)

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

Flying isn’t always fun but my flight was good and that’s saying alot

This flight was significantly affected by poor wifi connections. I couldn’t get my work done because the wifi kept dropping. Even texts were not going through. There is no seat power in premium class either. I fly a lot. Today was my 10th flight in 4 weeks. This was by far the only flight that was sub par.
