Crew was great, flight was uneventful (which is what you want!), would like media in the seat backs in all airplanes ..but all in all it was a good flight experience.

Crew was great, flight was uneventful (which is what you want!), would like media in the seat backs in all airplanes ..but all in all it was a good flight experience.

Unfortunately, an issue occurred where a delay impeded me from making my connection in LA. I couldn't get a flight home until 10 hours after my originally scheduled flight. Once I finally made it to DFW for my connecting flight, my next flight was delayed. I was supposed to be home on 12/23 at 9:00 p.m. I didn't make it home until 12/24 at 11:00 a.m. I was given the choice to either take a flight the next day or the flight that way 10 hours later. I wasn't given an option for a hotel if I stayed overnight. I was also denied the ability to go to the Alaska Lounge due to the delay. It was a very uncomfortable experience. The only seat I was able to get on the next flight was in a row where the seats couldn't recline. After an extended wait at the airport, this was very frustrating!

We don't have food or entertainment on this flight. We were late boarding but then arrived in Yakima early. Kayak sent me a delay notice but we weren't delayed.

I paid $49 to select my seat---6A a window seat just behind first class. When I started to get on the plane I was told that my seat had been given to someone else and I now had a middle seat. They finally gave me an aisle seat. When I told them I wanted my $49 back, I was told I would need to call alaska and fight with them to get my money back. And when i was on the flight people going by kept hitting me with their bags. I have tried calling alaska twice to talk about a refund but never got thru to the right person!

Flight crew had the courtesy to ask passengers from my first flight to allow those of us disembarking to go first so that we could make it onto our connecting flights. Worked like a charm. Both crew and fellow passengers working together for a better outcome for all.

We missed our connection to Portland and ended up having to drive.

Spent extra to choose my seat. Found a window available so grabbed it. They did not mention the row didn’t recline. Had over 5 hour flight stuck in a straight back chair. Traveling for funeral - needed to rest and couldn’t get comfortable (row infront of exit😒 should have realized but wasn’t thinking I guess).

You an Kayak offered travel insurance. I had to cancel are flights which I well say was easy an I got my money back. BUT not the travel insurance Kayak or X cover has keep the money. So why I never went on the fligt I cancel way early. I know one thing I'll never go to kayak again.

Check-in was easy, I did it from the app. Boarding was easy, the crew was great. Santa Barbara airport had a disabled plane so we had to land in Burbank to refuel. They kept us well informed, and everyone was great. A very entertaining person from the Burbank airport got on and told a few jokes.

I had to miss that flight as my first flight was cancelled in Idaho Falls. Bad day all around . Couldn’t be rebooked!
