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.

Terrible experience resolving missed connection after flight was delayed. 3 hour queue at transit desk, not enough staff, no organisation, worst ever flying experience.

Qatar Airways did a very good job. Flights were slightly delayed with boarding but pilots made up time by arrival. The food was OK, no better or worse than other airlines. Although it would be nice to have three meals during 16 hours flight instead of two.

Our male flight attendant was top notch - wish I could remember his name. Boarding is never fun when I have to ride the shuttle to the middle of the tarmac and pull my carry on bags up the stairs to my seat. My knees are banged up and my shoulders give me pain, so the flight started off poorly. The seat leg rests don’t recline completely so that makes is difficult if not dangerous to get in and out of the middle seats. The entertainment system touch screens prevented one from seeing the options. They are old and the software needs to be updated. I was on six planes in the last two weeks and able to see the flight progress without any stress. Couldn’t watch anything else. I do like Qatar Airways, just not a fan of a few things.

The rows of seats in economy class are seriously close to one another making eating and resting just about impossible - there is hardly any legroom. Anyone larger than average size would have an incredibly uncomfortable flight. I had to basically share my seat with the lady passenger next to me as she was too big to fit into her allotted seat.

Food was good, attendants were friendly. Seats were not comfortable. Did not receive any amenities such as eyemask or earplugs that would have helped sleep. Additionally a large group of passengers boarded very late into boarding and were a disruption for almost the whole flight. Flight attendants did their best but the kids were making so much noise, kicking seats, and half the time no adult was sat with them so they weren’t being managed.

I staff or crew they were very friendly and humbly, they done theirs service very well, I appreciate them and thank you to the company or Qatar 🇶🇦 Government for providing as good service in their flight ,once again, thank you 😊 🙏 😀 😉 👍

Crews are very rude and unhelpful. Cramped seats in economy. Foods are useless

Lovely aircraft and I flight entertainment. Good leg room. Full flight crew struggled a bit

Food not good as good as last time flew with them

Seats very uncomfortable, impossible to sleep. Food average, bakery items not fresh. Pockets in seats not large enough to hold a book and a few other items. Cabin temperature too cold, even with blanket. Good selection of movies. Other than that 12 hours of torture!

Not good because in this cancelled and then rebooked flight BA put me and my husband in both middle seats when we were originally seated together in original flight and i was in aisle. I hate sitting in the middle. BA food needs to be better. It was just ok. Thanks though to screw and everyone one for safe flight

Crew members were thorough in checking seatbelts and whatnot which makes me feel cared for because passenger safety is a main concern.

I was sent an email that said my card payment was not verified. When I spoke to an agent , he said my card was not verified and the flight I thought I had to booked was no longer available so I booked another flight on another airline(United). Later I got flight updates , etc., concerning my supposed first flight. So if I was charged for this flight on British Airways/American airlines, I need a refund.

The crew made it a great flight. They were friendly and attentive. They made me want to fly British Airways again.

BA has not been handling priority luggage with any special priority. This time our luggage was distinctly very slow to arrive, well after the first half of items to arrive. Business class flights cost a lot and it would be nice to have that reflected in the speed of baggage handling! (I note that this has worsened in our long experience of BA.) On a different note, we spent 2.5 hours on the plane after landing because of an airport mishap at Boston Logan. The pilot provided reasonably frequent update but more could have been done to ensure passenger comfort, such as more beverage and maybe snack services.

I purchased premier economy seats but I was seated one row off and was sitting in economy my bottle of water and cookie did not compare to the menus handed OP it in premier.

Flight was excellent, staff was great. My first time in first class and it was very relaxing and comfortable.

They are disorganized….show your flight info half an hour before take off, so you are running all over the place. Customer personnel are not helpful, and act like you are bothering them when you asked for assistance - very rude!!! My very first and last time flying with British airways… good thing we have other options.

There was no entertainment offered or expected, so please disregard my readings of that component. The flight was fantastic. Efficient boarding, takeoff, and even early arrival!

2 hour delay with very little information given. Horrible service by BA employees at Heathrow after we missed our connecting flight. Extremely disappointing experience!
