The boarding pass had no gate published and there are many fewer large boards with arrivals and departures I almost missed my flight trying to find the gate

Everyone was so kind, flight was wonderful, check in and baggage were easy. Thank you guys so much for a great trip

For such a long flight, Tampa to Seattle, was shocked to learn that no food was served. Also, there were no TV monitors to be able to watch a movie.

The staff at the check-in counter was responsive to the long queue and intervened to redirect the traffic: foreigners can't complete check-in without human agents; that is the real line which moves quickly enough. On-boarding and off-boarding were smooth and civilized. Overall the operations were efficient and the experience was pleasant.

Ok, but nothing special. Long flight with no blanket/pillow set.

Flight was delayed by 3 hrs. Forcing missed connection and overnight stay. Terrible.

Made our reservations 6 months ago. When we arrived at the airport we were informed they no longer have assigned seating. We were placed in the last row next to the restrooms. Our seats did not recline. I do not like the fact you are assigning seats. I don’t feel it’s fair. People who make last minute reservations sit in the middle seats. It’s did Southwest now have assigned seating and you assign seats. Even Southwest was more fair than Alaska.

We tried for days to use online Alaska Airline app we needed to know what Gate to depart from . When we got there we were given a paper boarding ticket with the wrong gate on it . We almost missed this flight . It caused great stress and caused a health side effect. The previous flights April 24 started hour late mechanical issues . We were not allowed to depart plane in time to get correct gate and missed our flight .

Check in went smooth, flight was on time and our checked bag was delivered in a timely fashion.

I had to cancel my trip due to medical reasons. I have been unable to cancel online through either Kayak or Alaska Airlines.. I am trying to get my insured trip reimbursed by XCover. They are requiring a notice of cancellation or not using to get my refund. Please help me get that information. I have been unable to get this information from either Kayak or Alaska Airlines.
