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

The flight was again delayed for more then 2 hours with some lousy explanation regarding the reason of the delay. Although the flight was delayed for more than 2 hours, no refreshments were offered (according to EU regulations). Last 4 flights on KLM - always at least 2 hrs late. So be prepared that you cannot plan anything with KLM.

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

Overall a good experience. We were disappointed when we had to check our carry on due to the plane being full. KLM hadn’t notified us and we had valuable items in the carry on but they still made us check it. Some of the food was great and some was mediocre. Crew is really kind and funny.

Mostly fine. Minor delays departing and arriving. Quite a cramped plane, not so much as regards legroom but very narrow seats. Quiet nice food. Non-working USB charger. Flight attendants were helpful but not particularly proactive — one had to work to get their attention (but all was fine once they notice you), very Dutch style:)

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.

One of their staff was so rude with discriminative. Such a reputed airline shouldn't hire such kind of arrogant attendants.

one of my bags was drenched with fish smelling water and all my new clothes bought at dublin and the 23kg checked in bag were all gone waste with very pungent fish smell and also having stains

Short flight so not much to rate. Surprised I had to pay for a soda.

the room on the plane was good but that is because flight not sold the other three seat and I had room. the food in terrible.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

Very good need to offer better choice of food for business

There were a lot of empty rows. As a single passenger I should not have been seated with 2 others. The WiFi didn’t work. The Kosher meal was awful.

Both flights were delayed due to maintenance issues. Because they where late boarding all four of our bags where left behind on our last connecting flight.

Thankfully not a full flight so although my headphone jack wasn’t working 100% on my window seat, I was able to move to the aisle seat. Food was fine, nothing great but tasty enough. Crew were friendly and made enough rounds. Always have a decent experience with Aer Lingus

Great hospitality and service! Seats could always be cushioned better.

The vegan meal was pretty horrible tasting and the staff did not bring me breakfast and no coffee and asked. the connecting flight from dublin to bristol was much delayed.

Customs is always a challenge. The customs officials were real humans, which was nice-not robots programmed on angry 😊. If you’re in a hurry to get through you’ll be stressed out. Allow yourselves plenty of time and it will be a stress free experience.
