Flight was ok but lack of communication cost me to literally beg to be put on another flight as connecting flight had departed

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.

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.

First of all we couldn’t check in online, then we learn at the airport we were on stand by for KLM’s mistake of overbooking. The seats were not comfy at all. Our luggage got lost.

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

The service was great. However the lounge only gets passing grade

I don’t like that an equipment change caused my seat to change from 23A to 44A. The boarding was also delayed. The crew were excellent, however and very attentive. The food was not bad.

Our flight crew were terrific. And they handle a difficult passenger with finesse.

Excellent, Lima to Paris. But Paris to Amsterdam, delayed, missed my flight and KLM treated its missed flights passengers very badly, terribly bad. No hotel accommodation given. Passengers were told to find their own hotel accommodation and claim at reasonable rate and left the booth and literally with armed Police Officers listening to passengers complains. For three hours, after moving by Uber from hotel to hotel and calling and booking online, no hotel was available. I had to return to the airport and seat/sleep on the benches, suffering the cold, and rats running around until my new allocated flight the next day. It was the most terrible KLM treatment even seen and being a Business Class passenger. Still mentally suffering to date as a result.

I bought business class tickets but the seats are exactly like economy with no comfort seats nor an empty seat next to me provided. Very poor, low quality airline.

I don't understand the concept of paying to get your personal luggage onboard and then asked to check it in.... either sell the space or don't, its a hassle to carry those all through the airport just to make a check in at the last minute.

Old airplanes small seats expensive tickets, not as expected overall and not comfortable according to the price

It was an OK flight with below mediocre service by their flight attendants

Wasted a lot of time trying to find the CDG lounge - it was not next to the connecting flight gate like the Air France staff said.

My experience was good overall, the quality of the food really decreased! There used to be a choice between meat and fish now it’s between chicken and pasta! In the choices of entertainment meditation has been added which is very good. Soft chair workout to improve blood circulation and avoid phlebitis should be added.

The only reason the overall rating wasn't "excellent" was due to problems in claiming luggage. The bags are delivered to the main area (Cinta 35) for domestic passengers, but to a DIFFERENT ROOM for international arrivees. After waiting 30 minutes, someone (who didn't appear to be from Air France or the airport) told us to go to another area. There we found our bags, which appeared to have been awaiting us for a while. We had to go through a bag check before leaving the airport. If we had been alerted to this possibility, or better yet, been to go directly to Cinta 34, we could have eliminated quite a bit of waiting.

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.

The boarding process seem to take longer than necessary, resulting in a 20+ minute delay

It was too cold in the plane my feet froze

Service was excellent. Food and drinks were very good except for a greasy lump of a donut at the end of the flight that left us both feeling internally disgusted.

No meals included on this long international flight. Most airlines will offer you a meal when flying internationally. Not Icelandair. Your included choices are water and coffee. Poor customer service. The airport was also very confusing.

Best smelling onboard bathrooms ever. Even after use the whole flight. Biggest overhead bins. Most legroom in economy class. Great Icelandiic music. Really nice staff. Icelandair is awesome! (Don’t fly Air Canada! During the strike they lied about no flights available (I booked this flight myself) and hid the process to get money back on their website by obscuring menu titles, then made it difficult and time consuming to fill out. I’m Canadian. Don’t trust Air Canada!

Everything sucked. No food, one small glass of water, a tiny coffee, 5.5 hour delay with no customer service. Would never recommend flying them.

The crew was wonderful at check in, the gate and on board. Felt the luggage had more room than the passengers. The seats were smaller than most domestic U.S. airlines. I'm only 5'2" and I had little legroom. There were only 2 bathrooms in coach. Needed more. The flight was very smooth but not the most comfortable.

There was no lounge at Boston for us to use. Typically flying first class overseas comes with lounge privileges. The seats did not recline even a little. My headset only worked on one side. I felt like I was flying on Ryan Air, not Icelandic Air.

Boarded with no problems. Sat on the tarmac for an hour before taking off. We were the last ones on our connecting flight. Didn't think we were going to make it. Our flight to Iceland was similarly delayed. When we've flown other airlines, pilots have tried to make up time while in the air. This doesn't seem to be something that Icelandair does. We made all of our flights, but it was stressful and we didn't think it was going to happen based on the time we arrived.

Great experience on Icelandair flight from Newark to Amsterdam by way of Reykjavík. Courteous and professional staff. Food was solid. Service - outstanding. Cabin was a little warm.

Excellent experience in every way, from ground crew helpfulness, boarding experience, inflight service all the way to modern equipment. My new favorite airline. I wish I could fly with them more often.

For a no frills flight this was surprising comfortable. The crew were helpful and nice. The flight was smooth and there were no delays or issues which I haven't had on a flight in a long time. I would definitely fly with them again.

The flight was canceled by play less than 24 hours prior to the trip, and I was unable to re-book. Have not received a refund for the trip despite filling out the appropriate form.

Was was cancelled less than 24 hours prior to my scheduled departure by PLAY. Despite my attempts to rebook my travel, I encountered significant cost increases that rendered this option unfeasible. In accordance with EC Regulation 261/2004, airlines are required to issue a full refund for cancelled flights within seven days of the scheduled departure if a refund is requested instead of rebooking on another flight. It has been three weeks without a refund or an answer

It would have been better to have USB charging ports available on the longer haul Flight that one of 2 hours

Was very good Staff was great. No tv monitors tho. So long flights make it longer

The worst. No free beverages. No entertainment on an overseas flight. Not enough space. Never again.

Play is affordable! Only way we fly from the states to Europe. Left late but arrived on time

have screens on backs of chairs...offer free snacks and water
