Get to the Lihue airport 3 hours before the flight because there are multiple security steps and extremely slow security processing. Even if you have TSA precheck/global entry.

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.

We got window seats and there was no window to look out at very disappointed in paying for a no window seat

We took off on time and rose into the wild blue yonder safely, and landed at our destination safely eighteen minutes early. In between we enjoyed a smooth flight and wonderful service by a great crew. Flight attendants and pilots made sure the trip was a memorable and happy experience. Can’t beat that!

Affirmed my disability by allowing me to board when most accessible. Very parable, helpful and friendly staff. Smooth flight overall! I always fly Alaska when possible! Thank you!

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.

Seats in Delta Main are unbelievably close to the seat in front of. Hard to get a backpack under the seat.

The agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

In ATL they have two sets of departure screens. Follow what is on your airline's departure board - the ATL Airport Authority departure board had completely incorrect details about the gate assignment for my flight, which would have made me miss boarding.

Flight was delayed it was hot while sitting on the plane, one engine was working on the plane until they had to do some jimmy rigging down the runway in order for the other engine to charge up. It was ridiculous

The flight was very good and the staff was very friendly and helpful!

The only thing I would say is we tried to get on a standby earlier flight, but with our fair we couldn’t. That seems senseless to leave with open seats..

Very easy to use and convenient, you can perform any action within the same portal

In a world of delays, Delta was on time both ways! Boarding was fast and efficient. Staff was friendly. AND wifi worked.

WiFi didn’t work. Flight delayed 3 hours Crew members were illiterate Seat lean back did not work.

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

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!
