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.

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.

Ad experience - been flying many years with them but they are losing out to other carriers with their service and bagage / seating policy. My 2 12-yo kids were not placed with the parent. Absurdity.

Short flight so it was okay. Nice crew, all very pleasant and professional. We were near the back in row 27 so just as we got our drinks, we started our descent so had to drink very quickly!

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.

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

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

It was okay. The airplane was a little smaller than a flight from Thailand to Helsinki.

Wish that everyone would board the back of the plane first. Also let kids on first. The gate wasn’t open at arrival and we waited 45 minutes to takeoff. They made up for time in the air.

This was an absolutely exceptional flight. The flight attendants were extremely attentive and very friendly. They seemed to go out of their way to make us comfortable and to make sure that we had everything we needed., We were in business and were very happy with the size and the details for our pods. We would definitely recommend Finnair and will definitely be flying with them again.

We had an excellent trip with Finnair. This was our first time and we’re very pleased. The only issue was with the boarding - it was a little bit confusing and needs a little bit of streamlining.

Crew very lovely. Arrived an hour late due to bad weather. We were given new tickets to an other flight but it could have been organised better, so we did not have to run through the whole airport to.

Flight delayed over an hour. They said they would hold our connection but then did not.

Major problems checking in at Alaska counter. They could not find our booking code because it came from Finnair.

Do not use KAYAK or Finair for future travel. Unless you purchase the tickets directly from the airline, you were going to have a difficult time checking in. Kayak canceled my flights twice and ended up causing great difficulty in me getting back from Europe because they double sold my tickets between American Airlines and Finair. The event caused significant delays and led to me having to rebook my flights.

The staff were all particularly great. The plane was clean and fresh. The bassinet worked great. It was all very nice.

Boarding uncomfortable. Stewardess said I would have to check my carry on as there was no room in the overhead bins. Another passenger helped me find a spot.

It was good. The air plane is clean and staff were friendly.

Worst airline I’ve ever flown. Delayed 5.5 hrs, missed connecting flight, and missed an entire day of vacation. Zero customer service

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.

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.

Good service. No complementary food for international flight. WiFi kinda pricey. Got the job done for the right price.

The plane was very small and the aisle was so narrow that every time someone walked by they rubbed against me, so it was very uncomfortable.

Everything was good. Only issue comes from being vegan and flying. The food options are super limited.

For a four hour flight, I was disappointed that everything was for purchase except for coffee, tea, or water. The disembarking in Iceland was so inefficient and time-consuming. We landed and stopped in the middle of the tarmac, had to disembark in the rain, and then squeeze into a bus which took us to the airport. Crazy! How does that work in winter?

Paid for a Premium seat...minimal recline, no footrest. Maybe slightly wider than a cheap economy seat. Zero chance of getting any rest on this plane
