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.

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.

O’hsre taxi and deboarding took 40 minutes. Needed 20 minutes extra time between connecting flights to avoid running through terminal.

Overall a good experience, but no wifi available for free or for purchase and we got wet from condensation or other water source during descent.

Booked through Kayak Business, had a seat in middle and towards back due to booking rate, not comfortable.

Was great in general, try to respect time and excuses when slight changes have been made, appreciated!

A long delay. Don't travel late in the day.

Super friendly with lots of drink options an entertainment. Friendly crew.

Standard flight with a drinks and a snack- overall very quick flight. The flight attendants were very strict, bordered on rude.

Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time

Delayed - weather wasn't bad at either end. Also sat on tarmac in ORD.

They told us yesterday APR21st that they were cleaning the plane and we got delayed. After that they said they didn't had any crew for the flight so they cancelled the flight till next day.

not sure why you ask about food, I n3ver get food on flights except maybe cookies or pretzels. wifi was slow and in and out most of the flight not good.

Cancelled BOYH legs of our flight home 30 min before initial boarding

Cancelled the flight half hour before boarding. Then cancelled the connecting flight too.

Left early arrived early..right amount of talking from pilots..of course had to love the biscuit and water!

I would like a refund for the extra cost the seat I paid for. An oversized person sat next to me and I couldn’t fit on my seat and had to move to another seat.

Boarding gate at LAX was too crowded—two gates next to one another

The flight was delayed about an hour for a maintenance specialist to approve the maintenance repair

This flight was delayed but it worked in my favor because my Atlanta to Dallas flight was delayed.

This was a hard flight. 3 delays out of OKC (1 on the Tarmac). Delay in Atlanta coming to Dallas. total travel time was the equivalent of driving from OKC to Atlanta.

Like: flights are on time, good boarding process Can improve: planes are old, improve entertainment and make space more comfortable

Frontier scheduled a 40 minute connection in DEN. What they failed to mention was that they “close the doors” 20 mins prior to departure, which means you only have 20 mins. Not enough time. Possibly against DOT regulations. Filing complaint.

Flight was scheduled at 9:40pm. Got delayed to 10 am, the next day. crazy

The bag check, flight check-in, and onboard experience convinced my wife and me that we will actively go out of our way to avoid flying Frontier Airlines in the future. At bag check, we were informed that check-in could only be completed via the Frontier mobile app. Unfortunately, the app was extremely frustrating—sending us through repetitive, confusing loops that repeatedly forced us to decline add-on services with nearly every click. While most airline apps upsell, this one felt intentionally exhausting. As the process dragged on, we became genuinely concerned that my phone battery would die before check-in could be completed. We approached the bag check staff—who were standing together talking—and explained both our frustration and our predicament. They laughed. Later, my wife described the interaction as “gaslighting,” which felt accurate. We were then informed it would cost $25 per person simply to have our boarding passes printed. From that point forward, the tone of the experience was consistently hostile. The bag check employees were condescending and combative, behaving more like bullies than customer service staff. Unfortunately, that same attitude continued onboard. One flight attendant argued with me when I attempted to stow my backpack in the overhead bin. I explained that we had each paid $75 to check our bags specifically so we would not need to use carry-on space and could have adequate legroom. She demanded to see my ticket, pointed out that it said “no carry-on”—which I acknowledged—and I reiterated that this was precisely why we paid to check our bags. Her response was, “I don’t make the rules.” She then walked away, but not before asking if I “truly wanted to fly back to Chicago today?”—an unnecessary and unmistakable threat. It is also worth noting that despite booking our tickets together in the same transaction, we were not seated together. Upon our return to Chicago—where we could once again sit together—we compared onboard experiences. We both remarked on how unhappy the flight attendants appeared and how each of us was separately asked whether we would like to purchase a beverage. We declined. At no point was water mentioned as an option, leaving us with the clear impression that even water came at a cost—or that complimentary water, if available at all, was deliberately left unmentioned. Overall, the experience was shocking and deeply disappointing, but it was also a profound learning experience—one we will not forget and will not repeat. -Steve

Plane was hot and miserable and the crew was rude!

12 hour delay required getting on and off plane 3 times - would have at least liked to have been offered a snack or drink

They didn’t offer a water, even after I asked

They switched our terminal 3 times and we were delayed for four plus hours!!!

It was an early flight and most people napped/slept and the crew let us which was nice.

The crew acted like they had never done this and kept barking passive aggressive orders at people. + the security line + the delay + sitting on the tarmac for 2 hours + none of the apps or signage updating with correct times

More inflight connection. And leg space is horrible. And the paying for baggage I'd ridiculous!!!
