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.

4.0 OkayMarcel, Oct 2025JFK - AMS
Read more KLM reviews

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.

Couldn’t get boarding pass in SLC even with help from a redcoat, so had to find a desk in AMS to get boarding pass. Technical problems so not sure why. Very inconvenient. The KLM app is not as user friendly as most apps. Also had to wait almost an hour on the tarmac for a fuel truck, which caused us to miss a connecting bus in LUX.

KLM remains a quality flag carrier airline which maintains its standards whilst all their competitors are lowering theirs.

The baggage drop-off in Stuttgart is bad: after online check-in you cannot use the automated baggage drop off as indicated on the website. You can use the terminals but have to cue to 1 of three open and slowly working counters to drop the bags. took about 45 minutes wait time.

Our first flight was delayed so we missed our connecting flight. However it was easy to book a later flight on their app.

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!

Klm start boarding while somw air issue in the plan

I appreciate that KLM was proactive in informing me of the 2 hour delay which enabled me to replan my travel. It was a bit stressful not knowing whether my connection from Montreal to Ottawa was happening. But the ground and air crew did a good job at comforting and assuring me.

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.

Flight left on time. Boarding was easy. Arrived to EWR 30 mins early. Luggage was deplaned in good time. Overall a very good experience.

Flight from Rome to SFO was excellent compared To our flight to Europe from SFO. The food was much tastier. You can see how UNITED is skimping, though. Instead of getting something mid flight you had to ask for it. It was not automatically served. There was a cookie at the end of the arrival meal, for example that tasted like it just came out of a box. They used to serve a little container of nuts, now … a tiny container of nuts, mixed with pretzels. This was business class that you really have to pay for! But this is minor complaints compared to the overall. My major complaint is the position of the even numbered seats by the windows. You have to turn around to see your window & the positioning as some other controls are harder to get at. This is compared to the odd number seat that are perfectly aligned.

The person I bought the ticket for didn’t make the flight.

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.

Excellent flight. Smooth, efficient boarding. Quick flight. Arrived early at STL.

After boarding the plane in Chicago, the passengers were told that there was a technical problem with the plane. Passengers remained on the plane as they tried to fix the problem. After what was probably an hour passengers were told that there was a need to change planes as the problem was not solved. Passengers disembarked and boarded another plane. After taxing to the runway and waiting for takeoff, passengers were told that owing to the thunderstorm the flight was unable to take off but would try and reroute. After some time passengers were told there wasn't enough fuel for the new route and the plane had to return to the gate for additional fuel. after another log delay the flight got underway. On the plane there was food, drinks, ice or entertainment. We were a glass of water, which appeared rationed. Flight arrived about 5 hours late. The pilot was fantastic and communicated with the passengers throughout the ordeal.

The food quality sucks. One must starve if they do not eat flesh Or wheat based products Some variety would be expected. The trivial amount of snacks and or food is inhumane

Excellent all round, first time flying United. App is very helpful.

Wish some foods provided rather than just biscuit/cookie for flight more than 2 hours

Wish a flight with more than 2 hours with some snack rather than just cookie/biscuit.

The flight attendant, a black woman with curly hair who sat near Row 21, was wonderful and kind.

It was good..clean, comfy seat. Friendly warm welcoming crew. Was able to check my cabin luggage at the gate which I was able to pickup in a decent time from baggage claim. The app gave all updates from delays to baggage claim info. Overall smooth flight.

Nice comfortable flight from Barcelona back to the states. The premium economy offers the extra room we need for my husband. The food was good and our flight attendants were excellent.

Flight was delayed leaving Dallas. Arrived about 2 hours later than scheduled.

Flight delayed and missed connection. Rescheduled flight cancelled after 6 hrs wait. Rerouted thru ORD, flight cancelled, overnight stay in ORD. Still in the air on new flight!

We are too tired and frustrated to comment politely at this point

Terrible. Our luggage was delayed and couldn’t be delivered for several days. We got bad information from the airline agents at baggage claim. We had to pick up our car so we wouldn’t be charged for an extra day. We got lost in the maze of airport parking. The baggage claim agents didn’t offer us any compensation for our extra time and expense. We are tired, hungry and very frustrated.

The flight was flawless and we even arrived between 20 and 25 minutes early!

Experience was great overall. However, the connection time between my flights (1hr 15 mins) was too short. We had to get through security check and US immigration in that time, and I made it to the gate just as they were announcing it was about to close. Flights with such a short connection time should maybe not be offered for purchase, or an advance alert would be helpful. Other than that the in-flight experience was excellent, especially the food. Many thanks!

The seats needs to be comfortables, at least please add more padding to the seats.

Incredible service. Incredible entertainment. I felt like they just kept serving us something new avery hour. My wife and I both had a joyous flight.

They out me in the baby row so I was surrounded by toddlers, they also did not send my luggage and was not able to book my connecting flight

I was so grateful for the kindness of the crew. They made a long trip very pleasant. Food was delicious. Many movie options

My flight from Dublin was delayed two hours which ment that I missed my connecting flight to Phoenix. American Airlines provided a hotel room and rebooked my flight for 7:30 AM the next day. I didn't get to the room until 11 pm and I had to be at the airport the next day by 5 AM. The airlines did their best but the schedule was challenging for an 81 year old.

Dinner was fabulous. Would have enjoyed a wine with it. None offered... for sale??? Breakfast was disappointing but adequate amount of food.

Excellent flight and crew. Boarding at Dublin Airport was a very difficult trying to find the right gate.

Dublin airport is big and US Customs and Immigration screening officers are is part of the process there. This eliminates screening upon arrival to US, however should be taken into consideration when playing your transfer. After all, pleasant experience enhanced by draft Guinness and Irish coffee at the buffet area near the gate. We loved boarding by the row, back of the airplane first.

There was a mixup with our tickets. They said they did not receive payment for them but yet we had seat assignments. We had to purchase last-minute tickets which cost us three times as much. that’s why they got a rated of a one.

Not my definition of first class. No leg room and barely any recline. The food was good. The crew was great. The comfort for the price I paid for London to Cairo was highway robbery. The Wi-Fi didn't work for me either.

There might be more food options for people who can't eat so much starch/sugar/bread/rice. Meat, cheese, walnuts/pecans for snack, maybe jerky or other kinds of meat-based snacks would be better than bread and rice and sweets. I had an extra chardonnay, which was fine. The entertainment was great.

Unfortunately, my flight was cancelled because of some sort of emergency over the Atlantic and had to return to London. While I think British Airways made every effort to mitigate the situation, I must say it was still pretty unpleasant. I do appreciate the fact, however, that British Airways put my safety first…and I think the effort to correct a bad situation was very sincere. But I think the process might be handled better in future.

Crew service was poor and very little difference between premium economy and economy. Disappointed.

My bags never made it on the flight and I now have to wait for them to arrive hopefully tomorrow. You can’t even track your bags in the app to see where they are since they didn’t arrive. You have to file a claim and then wait for them to inform you when you will receive your bag. We were already delayed for an hour due to baggage so I don’t understand how my bag didn’t make the flight.

One of the worst experience given the middle seat even asked for the change no one honored,boarded at the end and overall one of the worst experience

It was good although our flight to the UK was cancelled and rescheduled for two days later. This was after we were already seated on the plane. We missed the first leg of our trip. BA did put us up at a hotel and paid for our meals but we lost our hotel costs in Glasgow.

The crew was very nice and pleasant. We were very reluctant to book our flight with British Airlines because we had bad experience with their flight attendants on the previous trips, they were rude and not helpful.

I am a 25+ years American Airlines member. British Airways is simply above and beyond in every customer satisfaction category.

The seat pads are past there sell by date now and are uncomfotable. Also, with screens in the back of the seat, the seats shouldnt be able to recline as this puts rhe screen in your face.
