Its bumpy but I can say its safe flight ,Thanks Alaska airline for bringing me in my destination😊.

Almost 3 hr delay in Settle with very little information available to passengers. They boarded the plane and we waited for a long time inside the plane as well.

This was our first time flying with Alaska. It was a seamless experience, with comfortable seats and leg room. Staff were friendly and helpful.

Flight on time. Crew good. Seating Bad. Have to pay extra on a not cheap flight to avoid being next to toilet.

The crew was great! Passengers were nice. Just an fyi that I heard several of them complain that the snack was not gluten free. Many people got handed the snack and then promptly gave it back to the flight attendant. Might be good to look into another option as such a high percentage of people in CO and WA are gf. Cheers!

The flight was fine, but the Kayak app is terrible. I could not input my flight. I couldn’t use it for anything and it would not even let me try to add a seat once you purchased the ticket you might as well. Delete the Kayak app as far as I’m concerned. I’m done with kayak. Com

Food and entertainment not applicable - standard drinks and cinnamon cookies; crew did not do a song and dance for us so no entertainment. I like the slightly better leg room than American Airlines - at least it felt that way. Flight crew and atmosphere seemed more welcoming than American, too.

this was the THIRD time in four Alaska flights that were 2 hours late. Only one was due to weather. The intentionally posted each flight as only 1 hour and 55 minutes late so that they wouldn't have to give out vouchers. And then the flights all ended up more than 2 hours late. Makes United look like a premium carrier.

It was fine, mostly I was just happy to be on my last leg home. No in flight entertainment but that's forgivable since it was only a 2 hour flight.

Was delayed in Newark 24 hours due to mechanical problems. The staff was very helpful in trying to make the best of a trying situation. In SeaTac, they changed gates and times. Usually have no problems from SeaTac.
