Our flight from Raleigh to Seattle delayed by hour plus. We missed connection as we couldn’t get to next gate in time Then we waited till 2:30 plane and then sat on tarmac loaded for half hour then our luggage couldn’t be found finally found where it was 2 employees sent us in wrong direction

They were really helpful with every question and my kids had never been on a plane and the staff made them feel comfortable

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.

Tucson AS767 flight yesterday from Tucson to SeaTac international Flight left Tucson around 7:44 am My name is Tanya Blendheim and I had a horrible experience yesterday morning at Alaska Airlines desk leaving from Tucson AZ. The agent was extremely rude and questioned everything about my trip. First she said (in a less than pleasant tone) you know your flight boards in 8 minutes? And we stop checking luggage 15 minutes before boarding. I acknowledged the first statement, but said that I didn't know about the check bag policy. (Another passenger, a man, was right behind me and he was denied checking his bag, which made him have to go back to his car to leave liquids behind) I also needed wheelchair assistance for my friend. I ended getting the wheelchair myself. The agent also said I wasn't checked in, which I was. One person in our group was no longer flying. She also said I had to pay $40 to check my bag and that my bag was 6 pounds over. The thing is, everything she said to me was said in a sassy tone and that was not professional or necessary. There are ways of informing customers of what is happening, without being condescending or rude.

very nice blankets and comfortable seats. great service. Great flights.

I’m biased. I work at the airport and within these systems so I know how to be effective. On top of that part though everyone was friendly and helpful. Both legs of my trip were on time. My baggage was handled with care. Alaska’s part of my experience was top notch.

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.

A gentleman at the desk for my boarding from Seattle to Anchorage randomly selected me and told me they would need to check my carry-on despite having multiple lithium-ion batteries all of which were in communication devices essential for time in Alaska. There was ample overhead compartment space and I was lucky non of my equipment was damaged due to his unnecessary use of power. A quick check with the flight crew would have likely resulted in an answer that ample space remained allowing me to keep my personal and important items near by. I did lose WiFi twice and that detracted from my entertainment which I do not commonly use.

Flight was cancelled which destroyed the rest of our journey.

no lounge in Orlando while waiting for flight no inflight entertainment screens in first class

Flight delayed two hours , missed connection flight then connection cancelled- horrible experience with hotel

Omg the disaster at the security was on another level! “Go to this end, sorry closed now, go to that end”. Ridiculous! This took over an hour! As far as the airline was concerned although I booked nearly a year ago I couldn’t get my bag tag - stand in another 15 minute line or my seat on Hawaiian Airlines- 5 more minutes! Then my TSA status was denied. Like what the heck! Makes a person not want to travel with this amount of incompetence

The Honolulu Hub needs 2 to 3 times the amount of things to do as well as shuttles that transport to/from gates and terminals. Arriving from OCONUS locations; transferring to CONUS locations its a miserable experience. Fetching and re-checking bags, then returning to a gate across the airport take longer than any other large airport. If youre confused by what I mean, the process goes like this: Disembark plane Walk a mile to the main terminal Walk half a mile to baggage claim Wait 40 minutes for baggage Walk a mile to re-check-in baggage Wait 20 minutes for checking in those bags Fo back through the wrong TSA line because the signage is poor Almost miss the connecting flight because your gate is across the airport.

The checking was disaster, the crew wasn't behave well. It took us two hours to check in, after that thr line at the TSA was long, we barely make the flight. Bad airline

The crew were exceptionally nice and accommodating. My wife was tired after the flight from Haneda, Tokyo. They let her sleep and served her dinner later after she woke up, before we landed in PDX.

Horrible food and crew. Crew were laughing and talking loud while people were trying to sleep

Yall need to integrate your system with Alaska more efficiently. They booted me off the first flight because of a discrepancy on your end.

I liked the Starlink WiFi but didn't like how they said they were the only airline to offer a free meal and it turns out to be just a standalone sandwich and then charge for snacks to go with it. Rather have the free snacks like Southwest, but have the option to purchase a decent meal for a 5+ hour flight.

Unfortunately, I was put into the middle seat in the first row of premium seating. Sounds nice right? No! that is the worst seat in the plane. I wish I was in economy rather than be in that seat! There is no seat back pocket, no tray table, no charger. Nothing! so unless you're row mates are willing to let you share their basic amenities any flyer should have, you are stuck. It was the worst experience ever! And the flight attendant forgot to take my drink order. I felt like the forgotten flyer.

Delayed and cancelled flights were hard and very stressful, both ways!
