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.

Seats are fair enough for medium tall people. Good food all the trip. Fight attendances are warm

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

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

The worst airline. Cancelled flight 30 min before boarding and rebooked on flight after 3 days.

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 food quality is poor. The staff are very friendly and accommodating. The entertainment program was limited. I experienced a delay of 30 minutes due to two issues. Passenger luggage had to be removed and there was a technical issue with the stairs not detaching from the aircraft. The pilot managed to compensate and we arrived only 15 minutes later. The luggage at Dubai airport was very slow. I waited over an hour.

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.

I missed my connecting flight due to long lines at security and immigration. Need improvements

I felt the overall quality of the plane and food service was less than that of their partner airlines, United. An example was wine was served in paper cups in premium economy class. There was no real silverware, napkins or a welcome kit other than a pillow and blanket.

Boarding time was a bit slow causing the flight to not leave right at 5 pm,but other than that it was fine.

I like the frequent mails we get when there is an update. Please keep it up

I have traveled to probably over a hundred locations worldwide, but had only one mixup of airport in Shanghai. Until Iceland and Stockholm. Reykjavik has 2 airports, Stockholm 4 (!). Please indicate clearly when a departure flight is scheduled from an aiport other than the international aiport. That would greatly reduce stress. Thanks

in the front - higher class of business - sitting in the same seat (with one empty in the middle) is not acceptable any more. need the business class to be as we paid for.

More than one hour detail with no explanation and no compensation

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

we had to unexpectedly check a bag, the flight was late getting in

There was a two hour delay because of incompetence in scheduling fuel truck. Further, upon arrival in Roanoke, hand baggage was sent to baggage claim. We carry hand baggage because it contains valuable or sensitive materials that we do not want going through the baggage system. This is very poor and United needs to perform better.

I was at the airport on time , I checked in my luggage . The plane was delayed and the gate was change. The flight board did not give information . I did not get chance to fly. I am going to make a claim for it

Departure was delayed by 2 hours and passengers were sitting on the plane.

Never flown with LH before so all in all wasba good experience. Also good to know that approx 24hrs prior the flight opens up for being able to organise the seating free.

It was a short flight, no real service (which is okay). Very bumpy because of weather.

I'm Canaadian. I hate Air Canada. I used to give them a pass on their international service. No longer, They suck across the board now! Old planes, exhausted staff bad food and shitty entertainment. Your seats need reupholstered! Start with that...

This flight is always a cramped bus. The gate area was inadequate and announcements were hard to hear. The flight was delayed 45 minutes to an hour by a broken aircraft door, making our total delay from Vilnius 5 hours.

Good experience. Food was great and passengers helped rearrange seats so our family could be seated together

Great flight. Left on time, not very crowded. Quiet and the right temperature.

terrible. they cancelled the flight 1 day before flying out and just sent an email to inform the same. i had to scramble on my own paying more to find another flight.

No eye patches , socks given out for overnight flight! The snack on the short haul was a cube of chocolate! The seat was uncomfortable for a long haul - not enough cushioning!

We paid to have overhead carry-on baggage. When we got to the gate we were told that our carry on bags would need to be checked and go below because the flight was full. Notably we were nowhere near the last people to board and about 30 other passengers also had to check their carry-on bags. Other than that the flight was fine.

Very bad plain although I paid A business class ticket I was stuck in a stiff fixed seat without any entertainment or Wi Fi for 5 hours I will never ever book a flight on British airline.

Self check in Kiosk did not recognize that I had prepaid for my luggage. This caused a 40 minute delay even though I had my British Airways email receipt for the prepaid luggage.

Crew were very friendly and helpful. They explained to us in detail the delay in our takeoff due to the storm that rolled in from Belfast and did their best to make up the time. Always great to fly BA!

Staff were very helpful. The free WiFi for messages was also very useful to keep in touch

Crew was more interested on looking at their phones than welcoming passengers during boarding.

The crew was very attentive and kept busy serving a variety of treats!

Terrible. Missed my flight to final destination because of delayed British Airways flight. Had to spend 12 hours in airport and $1500 for new plane tickets

The crew on board were all very pleasant and happy to help. The flight had the old business class seats. The departure board in the business lounge did not update and kept on saying ' gate open' but never said boarding. When I got nervous about the departure time and walked to the gate I was told off rudely for being late.

Offered vegetable curry when it was actually tofu which I don’t care for.
