The food from Lagos to Amsterdam was was very poor compared to AMS-YYZ

The food from Lagos to Amsterdam was was very poor compared to AMS-YYZ

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

no issues at all... Kudos to the food. This time was really really good

The food was ok. The crew seemed like they were cranky. I had one guy get mad at me for passing in between the storage area to get to the other toilet. I can understand if it's not allowed but reprimanding me like I'm a student saying "This is the last time!" was not appropriate. During my meal time, there was a French family around me. No problems there but when we usually have meals, they are supposed to put their chair in the upright position. These people did not do it and the steward did not tell them to raise their seat in the upright position. However, I was told to do so! So, me and another person next to me had to eat with the monitor almost touching our faces. Furthermore, a lady in front of me was putting her feet up and preventing another elder passenger from putting her seat back. To make it worse, she was continuously hitting her back into her seat, shaking my monitor while I was watching a movie. A crew member did speak to her about it but then she accused me of pushing her seat forward! The crew member gave me a death stare and told me to stop pushing the seat forward. I did not even touch her seat at all, if I did, she would know it. Her boyfriend also stood up and tried to push her seat even further past the maximum decline to no avail. None of these people were reprimanded but the steward, some bald guy, was extremely friendly with them and did not even try to instruct them to do anything until it was time to land. I resisted the urge to really argue with them because I would have obviously been seen as the aggressor (I have no idea why). I hardly said anything on this flight except "more wine please" and "sorry" if I bumped into someone accidentally. Overall, it was an annoying flight and I had to resist the urge to yell at the steward and the people he was overly friendly with. The happiest moment of this flight was leaving it.

One of the vstewardeses wanted to bump me of the plane for absolutely nothing. There is CCTV in the plane ans everything can be verified. Very disappointing , you all will see, o other 5 years and the passangers who does not smile to flight attendent will be bumped off...

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 .

The plane was clean and the staff was friendly. Food and drinks as expected on international flights. The entertainment system was old style, with a pullout controller, and selections not as extensive as on other flights.

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.
