The flight was 45 mins late leaving, we sat without a/c for some of this, 2nd Meal was a slice of pizza. Movies were good.

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!

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

The flight was great, the only reason for middle scores on entertainment and food is that it was a short flight so not included (but snacks were served including alcoholic beverages free of charge). I would definitely recommend KLM.

Was trying to change a flight but told that Canadian and local klm systems do not interact so they could not access my booking. Overall I like klm a lot but if it was important to change flights I would be very frustrated.

KLM is my favourite airline. Never ever let us down.Staff are first class.

Pretty bad. Food was awful. drinks were scarce, as if drinking an extra drink would ruin the airline. attendants were not very helpful. likely Dutch "directedness" (I cannot be bothered). Crammed flight. Entertainment in very minimal dosage. Almost all old movies and series with 1-3 episodes only. Very limited number of options available. Jesus!! it seems you need to bring your own entertainment these days even of flights that are 13 hrs long!! I would and I will avoid in the future!

I travel frequently. The flight was late again... KLM should really try and be on time

The flight itself it was great nice food the crew were very nice and helpful, Checking in from Birmingham wasn't great long queues for bag dropped, And I had my hand luggage case taken away from me even though I requested to have it with me as I had breakables items. I was told I can not because of the length of the flight with no explanation at all no options was given for me to take my fragile items out of my case it was taken away with hold buggage I find the staff member who was checking me in very unpleasant !! Can we please be advise if the rules have changed about the the carry on hand luggage it will be easier to be advise on booking your tickect if we not allowed to take the hand luggage with me. Overall I had a good flight .

I requested wheel chair assistance , it was confirmed via email that inwoood get it but I didn’t get it . The last leg of my trip to Nigeria was the worst.
