Airline reviews

It was a terrible flight! We were delayed 2 hours just sitting on the plane on the way from San Diego to Raleigh. Coming back, we were delayed again in Raleigh for about 40 minutes, when we got to San Francisco, we got delayed again due to no gate available. We missed our flight to Fresno due to all the delays!!! We had to wait in a long line to get compensated to stay in a hotel and this was about mid-night! The staff that talked to us did not even apologize for the inconvenience that happened! We were already tired from traveling and we had to deal with all the delays! The company has no consideration of their customer's time. We completely wasted one whole day just dealing with this delay and had to get another sitter for our dog because we couldn't get home that night. This experience was very bad and I would not want to fly Alaska airlines again and would not recommend it to anybody!

The problem was going through San Diego, a trip that's become a new development.

Flight was canceled in good weather due to mechanical issue. Rebooked to flight to different airport in area that landed 7 hours after initially planned arrival. We had to jump through hoops to get taxi reimbursement given flight landed in different airport at 12:45 am.

Flight delayed by over an hour…not their fault exactly, but it wasn’t convenient either. Other than that a great flight and STUCK the landing!

Great - i’ve been flying a budget Airlines for the last several times. And this was a breath of fresh air. Enjoy the atmosphere. The complementary drink and snacks, free carry-on. It was a breath of fresh air.

They cancelled the 6am flight around 12:30 AM the day before. I was luckily able to book through another airline. I called for a one way fare refund, the new flight is much more expensive. I lost $$$ in the difference and this caused lots of stress. I intend to take action following my trip, really off to a bad start and I will never fly Alaskan again

My travel mate needed wheel chair assistance getting on and off, and it was excellent. Thank you!

I was disheartened that AlaskaAir would not accept my service dog and not only was I not able to have him on my lap for my anxiety but they charged $100 and made me keep him in a carrier - zippered up so not even his head was exposed. This is a disservice to people with disabilities and will never fly with this airline again.

Bad. Flight was delayed over 2 hours and the plane was sitting on the tarmac the entire time. We received no explanation for why the flight was delayed.

The flight was delayed multiple times, there was hardly any announcements or updates on the kayak app advising passengers of the gates and times of any current flight. Very disappointing as this was my first flight with this airline.
