Empty seats next to me - wish it had been for a longer flight!!

Terrible last row seats many seats available but no offer to move to better seat

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.

Great boarding, great short flight but no entertainment whatsoever and no wifi. Prepare to disembark by a staircase.

Transavia flight. Couldn't select seat or anything prior to flight. No connection with klm systems. Seats are very crammed. Extremely no frills.

Great flight because I upgraded to Premium Comfort. Made a huge difference in the experience.

The plane. Airbus A330-200. Comfortable for a 7-hour flight. Seats seemed to have more legroom. I was in row 17. Flight was operated by Delta but was better than expected.

The flight was delayed for 2 hrs. Because they didn’t have a crew to fly. And it is not a first time for klm to do that. Last time they cancelled my filght and rebooked me 3 days later. Not reliable airline

I thought KLM was the best airline but the Lima - Amsterdam was 1 hours late, the Brussels - Amsterdam was 2.30 hours late and the Amsterdam - Lima was 30 minutes late

The seats are too cramped in that plane. If you’re above 1,80m consider alternatives or first class I guess… There were no emergency exits to seat somewhere with more legroom

The crew were nice and courteous. Exonomy seats were worse than expected. Overhead bin space was non existent thanks to loose enforcement of the carryon size and letting passengers put up their purses jackets and backpacks up there leaving no space for others with a small conforming carry on. Food was not good at all. Perhaps worse chicken I ever had in my life. I had to have them take it after tasting how bad it was. Whoever made that should not be in food making business.

Flight canceled and rescheduled a day early when I was still on a boat in the Mediterranean. I was never notified that my flight was canceled.

The crew was very helpful and friendly. Food was good. The only issue was the legroom -- not great. The seat in front is also too close to see the entertainment screen properly.

Everything! Food was fabulous, all 4 flts were fantastic. Communication was great. Attendants were thoughtful & caring. My only suggestion would be to have a better selection of movies. If this airline flew to all the places I travel to, I would use them exclusively!

You are asking me for experience with a food - but there was no food provided in the economy class.

No crying babies the whole flight would be nice. Impossible to sleep. No free snacks , only the main meal

Very easy to self check in and on time. Friendly staff

Free Starlink WiFi for Eurobonus members was a very nice plus.

Good flight, clean, well mannered/respectful Staff, .food are OK. Affordable price range

Copenhaguen airport is not very efficient, signs are not clear enough. Too much walking.

Bad baggage and people management at boarding forcing me to dispatch my bad despite being the perfect size and respecting everything perfectly, whereas many did not and many free empty spots on the plane as usual… making me loose time and my planned bus at arrival to go to Geneva. Costing me 100 euros extra! So Brussels airlines needs to refund me

I never board the flight. My visa was delayed and when I tried calling Kayak, no one answer and I still have not heard from anyone.

Crew was enthusiastic. Meal was surprisingly good. They came to give water very frequently. Negative that the seat reclining didn't work

That was a short flight by the only time I could actually sleep

How can a national carrier and part of Lufthansa group not even provide complimentary water and a snack in such a long flight ?

The flight went well, only during the flight from Brussels to Vilnius I would have liked if they had at least given us plain water to drink.

Terrible seats. Whoever designed the seats should try taking a long flight in it themselves.

Food quality is deteriorating each time, last year was very good. I avoid the plane food lately.

Been flying on various airlines, all over the world, for 50+ years. The food on Brussels Air was easily the worst I ever endured.

my husband's monitor did not work. there was a visibly ill family in my husband's row.

Horrible seats. They were just coach seats with the middle seat blocked with a dirty seat tray.

we were able to make it to the connecting flight in Frankfurt to Copenhagen thanks to Lufthansa crew. The ground crew was waiting at the gate and received us and took us through special runway entrance and immigration check. We were on the plane at 10-09 am for 10-10 departure. Thanks to Andre and the other lady for mission impossible :)

Entertainment system is old. Food can be tastier Need to provide toothbrush and toothpaste at least when asked.

I flew from Brussels to Munich, then from Munich to Denver. The flight from Brussels was only about 2.5 hours and it was okay. But the flight from Munich was about 12 hours and we sat on the plane for a very long time after everyone boarded. I paid something like $75 for a “preferred” seat in economy and it was so cramped my knees rubbed against the hard shell pocket. You couldn’t turn your legs to the side because the passenger next to you was too close. I was on the aisle but couldn’t put my leg out because there was often traffic or carts. Maybe I’m expecting too much but on such a long flight I’d like to see more comfortable seats. I think it was a United A380 plane. I won’t be flying anywhere that far away again. My legs and feet are still swollen 4 days later.

Good with last minute upgrade Clt to Munich comfortable. Wish same offer had been there Mumbai to Munich

The full flight boarded early, and then we sat on the tarmac for a long time waiting to get our plane de-iced. The crew was professional and pleasant, and the flight was pleasant overall, albeit slightly delayed. I did not use any of the entertainment options.

They didn't board the luggage and cph has poor service. During working hours they refuse calls, outside working hours you can't contact them. Lufthansa doesn't help or support

On Time departure and arrival Entertainment system not very userfriendly

The flight was half an hour late, which is the new normal in Europe. Friendly crew.

The seat was very comfortable and great selection of movies. Boarding was a little chaotic and lots of standing in a crowd.
