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.

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.

Don’t fly with Alaska if you have a layover in Seattle. Guaranteed to screw you over. We waited at terminal S3 &were >2 hours delayed(mechanical issues)and told to change terminals to a different plane that required riding 3 shuttles to get to new terminal N14. Then they delayed the flight even further and changed gates again. when I went to the customer service in terminal N, the manager turned me away without apologizing & refused to assist me but mandated I leave her alone as her shift is nearly finished and insisted I totake another 2 shuttles to terminal C so I can just talk to another service rep while dragging my family of 4/ kids in tow.

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.

Everything was good. Please have a wheat free option for snacks in the future.

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.

Not delay for a few passengers. That was uncalled for. If idiots can't make the flight on time thats their fault. Why should I be punished for them? No more holding the plane for one or two people

How can I review what was denied to me. Instead of offering to let me pay for the ticket I got booted of my flight with no way home and no choice but to purchase another ticket for 12 hours later. Filing a complaint with the DOT

I like them since I live in Alaska and I don't have much choice

No service flight that took 5 hrs and a stop at an unscheduled airport. Crew and pilots did their jobs

Clean planes and not take my comfort class seat away.

Weather caused a long delay, but the efficiency and updates from the pilot were helpful. We were able to make our connection fortunately.

Planes were clean, no water or snacks on either flight.

Free & relatively fast Wi-Fi. Would've liked a wider drink selection.

I continue to be satisfied with Delta’s excellent service out of LGA. The digit id works well and gets me through security in no time. Whenever possible, I choose Delta.

Was revoked with Jet Blue due to delay from Kenya Air

Enjoyed it very much. Especially liked the free WiFi that Delta offers.

Smooth flight. Left on time, and got in 15 minutes early. Onboard video was great

For some reason, TSA Atlanta didn’t have my bag on the flight on time and they don’t have to provide Delta a reason for that.

Seat pitch is horrible especially on the 15 hour flight. Gate crew at SFO was Outstanding. The flight crew was also great.

Had a one hour delay due to mechanical issue. I didn’t think I’d be able to make my connecting flight, but they waited for me and greeted me when I arrived to help things run smooth.

6 1/2 hours from Tampa to SFO on a Boeing 737. Cramped. No Service. No real food. One pass for coffee at the beginning and a second pass THREE hours later. And check-in in Tampa was nasty even by United standards. And I am at almost TWO million miles on United. It's a non-stop. But terrible service.

MY FAMILY'S LUGGAGE WAS LOST FROM ROME TO BARI. I WAS THE ONLY ONE THAT RECEIVED MY LUGGAGE FROM ROME TO BARI. AFTER DEPLANING IN BARI, WE WASTED A LOT OF TIME AT BAG CLAIMS LOST AND FOUND REPORTING THE CLAIM AND PLEADING FOR THE BAGS TO BE DELIVERED THE NEXT DAY. WE WERE TOLD THAT IT TAKES 3 DAYS MINIMUM TO DELIVER. MY DAUGHTER AND MY GIRLFRIEND NEEDED THEIR PERSONAL THINGS AND WE WERE STAYING 3 HOURS AWAY FROM THE BARI AIRPORT. WE HAD TO DRIVE 3 HOURS TO THE AIRPORT TO COLLECT OUR LOST LUGGAGE THE NEXT DAY. WE ARE NOT HAPPY WITH THE EXPERIENCE

We had a delay, but thankfully I made it to my connection. Overall it went smooth

The flight had a delay but I made it to my connection. Flight was smooth overall

As I wrote earlier, poor planning and/or communication. At least twice, we were told that we would be boarding in less than ten minutes, only to have the flight again delayed at least another hour.

This flight is a quick way to get to Chicago, but a bit expensive.

Our flight to Rome, Italy was cancelled the day of and we were never informed. We only found out because I was trying to get into my husbands account and called to get his account number. Had to pay more for worse seating on another airline.

My service dog and I were asked to deplane just before they closed the door - clearly very last minute they couldn’t find the documentation that I have filled out many many times before that is for flying service animals. I purposely purchase 3seats (a whole row) since he is large and not all passengers want to sit next to a dog on a cross country flight. The plane departed with my husband on it!!! They made me fill out a hard copy of the same form and had to reschedule me on a later flight where they could find 3 seats together!! I’ve done this so many times before - clearly the error was on their part in a technology glitch - but really people - do better!! Very traumatic - and my husband had to wait for us when he landed ….so bad. Poor pup was confused and tired.

Ontario airport boarding was very easy to park and access, is clean and TSA took 10 minutes total. Check-in was a breeze and cruise was very nice.

American Airlines II: Delay Boogaloo. Multiple gate changes, delays, boarded and then MORE delays. I hate to say this won’t matter, but posting stuff about major corporations in 2026 is a post-modern “scream into the void.” Was multiple hours late coming home, so there you go.

Awful, tons of delays, I got into Chicago multiple hours late meaning I hit the very traffic I tried so desperately to avoid. Just empty apologies from American Airlines text alerts. Trash behavior from a trash airline.

The flight attendants were very friendly, efficient, and helpful. The plane was ahead of schedule, and it all went very smoothly. Thank you.

They lost my baggage and I am still struggling to the information and update

We got delayed getting out of DFW for broken overhead bins. Once the flight got underway the captain kept the seatbelt sign lit the entire flight despite little perceptible turbulence, preventing use of the rest rooms and any sort of refreshment service in the main cabin.

Flight delays for communication overall not a good experience uncomfortable on the plane. Person in front of me reclined his seat, putting them inches from my lap.

There were flight delays making our flight arrive at our destination after midnight didn’t seem to have enough crew or airplanes for the flights laid over in Dallas should’ve had plenty of time to make it to our next flight only made it because that flight was also delayed because our plane wasn’t even at the airport yet overall have not had a good experience on American

Flight left on time. Captain provided relevant announcements. We had to wait 45 minutes to desembark due to the ramp closed because of lightening.

Cancelled flight. Still waiting to get home for grand daughter’s graduation .

Boarding and crew were great, but seats are terribly uncomfortable. No food or entertainment options.

Everything went very smoothly! Thanks for a great first experience flying with small children!

Crew members great. Everything else a 0! Got on plane at 530am. Got de boarded for mechanical issue. Supposed to leave by 830 am. Zero communication from gate agents. Then supposed to leave by 230pm. Then delayed till 330pm. Still zero communication with gate agents. All they would say is if you have an issue call the 1800 number. You call and sit on hold minimum 45 minutes for zero answer. Finally board at 345pm didn’t take off till after 4pm! Sat in airport for 11 hours with 4 adults and 3 kids. Finally offered a $100 (we are sorry) voucher for next trip. Missed whole day in Florida had to change reservations in Florida! Absolute joke of an airline! And I usually really like sun country.

Booked through Kayak for $236. They canceled the flight unknown to me; retaining $100 for canceling it. Found out when I went to check in. Rebooked the same flight for $400. Incredibly disappointed. The Sun Country part was as to be expected. Crowded, no food, no arm room but got me where I wanted to go.

3 seperate extremely rude unhelpful staff. Delayed flight. Lost my bag

Sat between 2 big men. I was uncomfortable. Flight was delayed twice. About 2 hours altogether.

It was a good experience. I do wish the seats were roomier. Also, I did not like being charged for my carry on bag

Exceptional take off and landing in snow and wind…thank you to the well skilled pilots!

I liked entertainment system being downloaded on my iPad. The selections were limited but I appreciated being able to use my own screen. The flight was just fine. My only issue was both terminals being far from the main airport. Especially stoning at LAX near midnight and having to wait for a bus to take us to baggage pickup. Very inconvenient.

Just fine but comfort is always an issue since the seats are so close
