The flight itself was fine, food was expired and gross, staff were mostly amazing! KLM messed up rebooking for our first two flights that got cancelled and we almost didn’t make it to Amsterdam for an additional two days

The flight itself was fine, food was expired and gross, staff were mostly amazing! KLM messed up rebooking for our first two flights that got cancelled and we almost didn’t make it to Amsterdam for an additional two days

I think I previously submitted my feedback about flight lead Katherine in a different field by mistake. Please see those comments. Comments for Hyd to AMS are it was good. The flight lead and service met expectations for satisfactory high quality service but the flight lead did not stand out as exceptional as did the leads on the other two flights so I don’t remember anything specific one way or the other besides the fact I was satisfied.

Had to cancel and rebook, KLM connection was cancelled prior to departure, ended up flying to Munich on non-Delta carrier.

The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

They forgot to serve food and the crew was very unfriendly. Never experienced such a bad KLM flight. Usually fly from Toronto. New York was different.

Over 1 Hr delay. No APU so no AC on ground. Plane was hot during boarding and then they closed the doors over 20 minutes before engine start so interior of plane was steamy hot and stuffy. Could have been helped by opening doors until ready to depart.

My flight was delayed by 6 hours then I missed BOTH of my connecting flights, I then had to stay in the AIRPORT at JFK because soooooo many people also suffered from missing flights and there was no hotels available. I would like to be compensated for this experience! I had to stay in the airport for over 16 hours!

Cabin crew were excellent, very proffesional, polite and friendly, in flight snack was underwhelming, a packet of cheese biscuits, im sure KLM could run to a sandwich!

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

The plane was clean and the staff was friendly. Food and drinks as expected on international flights. The entertainment system was old style, with a pullout controller, and selections not as extensive as on other flights.

It was the hottest flight I’ve been on in a long time. The female flight attendants were not nice.

The flight was freezing cold. I had on pants and a sweatshirt, had to wrap up in the blanket provided AND put on my rain coat, and was still chilly. Have never been on such a cold plane.

They changed my seat assignment from window to middle. I have a physical need to sit by the window because of spinal issues. I unboarded in pain, I also was placed between 2 very large men. I am very disappointed and now dealing with the physical aftermath.

The crew were awesome and ready to help as much as possible. The gate agent in Atlanta was tremendously helpful. The delays were ridiculous. Getting home at 4am when I could have driven home faster was unimpressive. Being delayed for countless hours through the night wasn't a great travel experience.

I didn't really interact with any of the crew since we had a bumpy ride and no refreshments were distributed.

My flight experience was generally good, but the boarding process was stressful. I was pulled out of line at the gate during the photo ID check, and after being cleared, I was never given an explanation for the delay despite asking for clarification. This lack of communication was the only downside to an otherwise smooth trip.

The wifi was barely operable. just enough to charge me, not enough to be useful. I wasted 2 hours of time I could have been working. So now, I' have two hours of work this weekend to catch up on thanks to Delta's crappy technology. Plus I'm out the money!

For some reason, there was very little volume on the cabin announcements. You could not hear what the pilot or crew were saying.

Really hard to tell what was happening after my flight got delayed five times

Audio Visual Equipment lacking content and features. No connection ability for noise cancellation pods

I did bought anything… I don’t understand how this book appears to me . Ridiculous

I had a terrible experience. My flight got delayed from Atlanta to Chicago on Monday April 6, 2026, and that led to me missing my next flight to Brussels. United Airlines didn’t provide me with any accommodation for shelter. I had to sleep at the airport in Chicago. The next flight I was put on didn’t leave until the evening hours of Tuesday 4/7/2026.

Just a bad day to fly. Flight was delayed from scheduled 6:50 pm departure to 8:50 pm. Combination of factors mostly related to weather at the destination airport (which is where the incoming flight originated) which delayed the inbound flight over an hour. Once on board, we taxied but had to hold again on the taxiway for 10 minutes or so. We did not get wheels up until after 9 pm. The flight was smooth but about 18 minutes from our destination, we had to hold for several minutes more due to weather at ORD. We finally landed at ORD about 11:08 pm (accounting for the time difference, that was about a 3 hour delay from our scheduled departure time). It felt like we were never going to get to our destination. But the flight crew and attendants were very good. The movie selection onboard was also very nice. Got to watch half of a movie just during our taxi from the gate at ATL due to the delay!

Everything was great except for the boarding process. Everyone is lining up all at the same time and it’s hard to tell between the groups as they are way too large.

Gate agent at Frankfurt was terrible. She denied PRE boarding even as it was printed on the boarding pass. Refused to look at the boarding pass and literally shouting for no reason. Frankfurt airport has horrible and rude staff who avoids trying to answer any question at all. Overall, horrible experience.

Excellent experience. Starting with the agent at the Premier bag drop who noticed I was very early for my scheduled flight and offered to rebook me on an earlier flight with my seat preference. She would not let me leave the counter until she knew that all of the changes and new boarding pass showed up on my United app. At the gate, the flight boarded quickly such that we departed early and the flight was smooth. We arrived 20 minutes early at ORD and I was able to be home in time for dinner. One of the best flights I've had.

Cramped seat even in economy plus seat 10A. Over booked flight, no space for the bags

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

Great onboard crew. Boarding was a zoo, I got in line before pre boarding in Group 2, still had my bag force checked. WiFi was glitchy all flight. Seat and bathroom are both tiny unless you pay $$$ for first class.

The passenger in the row in front of me was listening to a political speech on his phone at full volume with no headphones and it was disturbing all of the passengers around him for several rows. I asked 2 of the flight attendants to speak to this passenger but they only shrugged. It was obvious that they were afraid there might be conflict and would not say anything. I had to take it upon myself to tell the passenger that he needed to turn it off or wear headphones as it was disturbing everyone around him not wearing their own headphones. I was very disappointed in the United flight attendants.

After waiting for hours of delays, the flight was canceled. We missed our flight to Iceland from Toronto. We tried for hours to get a reasonable replacement flight, but it was the next day before we could even schedule another flight days later. We had to cancel our anniversary trip because we could not get to Iceland on time to keep our reservations. We won’t be flying Air Canada again as they just don’t have the infrastructure to deal with cancellations.

They did not let us board because one member needed a transit visa, which was not evident at the time of ticket purchase.

The plane was dirty. It appeared that Air Canada did not know vacuum cleaners had been invented. Second, the overhead bins were about 1/3 or 1/2 the size of "normal" bins. That was a problem. The worst was disembarking in the weather in Montreal. I have cold agglutinin disease. That means my red blood cells clump together and then are destroyed when exposed, even by breathing to cold air. A few seconds of exposure can be dangerous. I am now experiencing extreme fatigue caused by the anemia from that experience. I should have had more assistance descending a narrow ramp and then traversing, even if only a few feet, of icy pavement. The blowing snow penetrated my facial covering and has caused problems.

Crew was rushed to get food out and left trash for a long time on our tables.

The entire aircraft was outfitted with comfortable business-class seats that featured luxurious reclining capabilities and built-in footrests for added relaxation during the flight.

Nice small trip, No food included in ticket, but beverages were for free.

Entertainment was not working. No free snacks. Seats weren’t comfortable

Getting on the flight we booked would’ve been nice to begin with. Nope, they cancelled the 10 am flight. Herded everyone on to the 5 pm flight which got delayed twice. Basically made it to our hotel at 11 pm. So we lost our entire day in Toronto. Paid around $500 Canadian dollars to spend the night in downtown!! While they save a boat load of cash herding everyone on to the 2 evening flights.

Air Canada cancelled our flight the night before and rescheduled us for a flight 32 hours later than our initial flight. That would have made us miss our events in St. Johns and throw off the rest of our weeks plans. We cancelled our flights and the entire week in Newfoundland. Also want a complete refund not a credit.

We were on a Canadian fishing expedition, and Air Canada lost our Sport Fishing Bag. They said it was delayed and said it would be delivered that night, but that never happened, and we haven't seen it yet, which is 5 days later. We had to rent fishing gear to enjoy our trip. We are extremely disappointed with Air Canada oversize luggage personnel. With the sport bad and 6 rods and reels, we are out over $1500.

It was not British Air, we were put onto Air Portugal for our London to Lisbon leg.

Very please with the seating that the Kayak staff booked for us!

The cramped seats are cruel and unusual punishment and may violate the Geneva code.

Horrible leg room - coach seating with empty seat in middle on a 3 across seating. You buy business class for comfort which includes leg room. Absolutely no entertainment options either. Awful experience

Very good crew. The seating in economy plus was excellent, and I slept most of the way. The diabetic meal that I requested was almost tasteless--about a 2 on a ten-point scale.--so I ate little. And why bother serving dinner to fliers at midnight?! I had eaten a meal at the airport six hours earlier. A good breakfast would be better.

They denied us boarding on our scheduled flight and experienced significant disruption to our travel plans because of overbooking the flight!

One of the worse flights. Departure was delayed by an hour. Boarding was disorganized. It was freezing on the plane. The crew was not very helpful. One of the flight attendants was literally marinated in some awful perfume,. And the food was uneatable, both dinner and breakfast.

Horrible service. Lack of courtesy and professionalism from some cree members

In economy and food was ok, but with limited leg space (and I was in a 2 seat configuration) it was difficult to eat with a tiny seat tray. I spilt wine on my trousers. First time on British Air (I usually fly Turkish Air) and in a 777. Heathrow was pleasant but changing terminals awkward.

I couldn't get my luggage after arriving to my final destination. I don't know if it's lost or whatever. I in stress right now
