The merging of Kayak & the airline’s website was not always clear. Both on their own provided adequate Information about the flight. I had some challenges retrieving the boarding pass. I relied on the agent & may have paid the baggage fee twice.

Hello, Our flight arrived late, and the flight we were to connect to the departure time was moved up. At first our flight was scheduled to arrive at 10:40, but it arrived at 10:56. Our connecting flight was scheduled to leave at 11:25, and it was moved to 11:20. Also the terminal was moved from N to S. N would have been in the same terminal as the one we arrived in-- to get to S we had to take 3 trains to get to. And when we arrived at the gate, around 11:15, they said the gate was closed and would not open it. We had come from a funeral in Boston, and the person that helped us get new tickets said, "did you come from a girsl trip?" No, we did not. We were coming from a funeral. This experience was not what we expected/wanted. My friend, because she had to run to S, got a migraine and turned pale. In addition, I paid an extra $70 for an aisle seat that was more upfront, to make sure I can get off the plane faster and make the connecting flight. The fact that the plane not only did not wait, but left earlier, is absolutely unacceptable. This was a terrible experience, and I hope that I can be refunded for this horrible experience.

Generally very good. Waiting (due to de-icing and traffic) in plane to take off was a put-off. But it's not the airline's fault. I find Airbus more comfortable than Boeing.

Smooth flight, on time despite Captain’s forecast of troublesome weather conditions.

The flight was a disaster. It is a 40 min flight and we waited to the tarmac for well over 90 min with no updates, while the crew tried to reconcile the seating chart of people on the plane to what their phones showed. Terrible communication, systems and experience. I would do almost anything to avoid taking another Alaska flight after the experience last night.

Leg and arm room are horrible. I am not a big person and found it tight.

The plane boarded late and arrived late which wasn't really ideal.

Upon arrival I was disappointed that the assist I requested to get to the baggage claim wasn't provided. The entire baggage area was not clearly marked and I wanted to store my baggage overnight, that wasn't available. I had to take it on the shuttle to the hotel!

The staff was extremely pleasant, and the ride was uneventful… If I were going to a place they serviced, I would take Alaska again

Kayak and Alaska have our trusted traveller information stored in our profiles. But, that information never made it to Alaska when it came time to check into our outbound flight. As a result, we were not cleared for TSA recheck. I was able to add in that information for our return flight and we had TSA Recheck on the return. I really expected Kayak and Alaska to do a complete job with our booking given the amount of information you have on file.
