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.

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!

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.

Boarding in NCL is really bad. I'm sure part of that is a directive from the airport that KLM can't change but part of that is due to KLM policy. NCL doesn't announce the gate of departure until 30 minutes before departure. However, when you arrive at the gate area, the gate agents file everyone into one long line and everyone boards from one line at one time. This line can stretch for 200m...easily. There is a separate line for groups 1 and 2 but you don't know it until you get to the gate area and agents don't announce/advertise it. Everyone else is grouped into one line. Are you in group 3? Doesn't matter...you board with group 5. Traveling with a child? Tough luck...you're stuck at the end of the line and board last. The last part is very annoying because none of the gates at NCL (with the exception of 1 used by Emirates) has a jetway. To board, you must leave the gate area, walk downstairs, walk onto the tarmac and walk up stairs to board the plane. Highly challenging if you're traveling with small children. That boarding process begs for a concession to allow people with children to board first because they will need extra time. But there is no such policy. Just a really horrible boarding experience all around.

Lounge was top notch h with great variety of food and drinks. Cabin crew were great. Smooth flight.

My seat 3G did not go down fully and the buttons were not working properly

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Security area in terminal 3 needs to be made much nicer. Less claustrophobic and use of glass and big ceilings wouldhelp

accomodating check in staff, friendly flight crew ( a crew member was speaking tactlessly and was overfamiliar with passengers

Seats need to be updated. Allowance needs to be made for dinner service at an alternative time

If I could fly Virgin Atlantic airlines to every place, I need to go, I would. Leaving Heathrow through the special virgin air entrance, security is completely white glove service. I love this airline. From ticketing agents to flight staff everyone tries to make it a wonderful & happy flight experience. I wish other airlines copied the positive culture of Virgin Airlines.

Premium was very comfortable. Food was delicious. I had specific diet requirement and Virgin Atlantic ensured it was provided. Onboard crew was very friendly and caring. Extremely smooth journey. I wonder how upper class experience would be. Perhaps one day, I will try upper class.

On arrival to JFK it to 3.5hrs to clear immigration, as only 3 booths open. Almost missed connection

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.

Generally very good. I think their service is better than some other big names I used to travel with. Their food variety is second to none - and you can place order beforehand. Their seating design is a bit awkward for service, I'd say. Flight attendants must be tall enough - long legs and arms - to reach the window seat passenger while crossing over the isle passenger. Also appreciated the variety on entertainment.

Lovely big plane. Excellent take off and landing. Cabin crew were so nice. Flight in time no delays

Los Angeles to London. 25th of April 2026. Business class. I was flying backwards with a complete stranger snoring next to me. In Business class. Males and females, strangers lying next to each other. Seats were backwards. I paid for comfort. I got dizziness and stress.

The crew has always been great on BA. They are very friendly and accommodating. I like that they have vegetarian options already in the menu. And the free wine is a nice perk.) I noticed (both directions of my trip) minor upgrades/ replacements needed on the plane itself (touch screen didn't work with touch; bathroom light didn't go on). However, this is one of my favorite airlines.

There was a delay for the San Francisco-London flight, but we were all informed via text and email. The staff was very friendly and nice and the food was good. I do recommend that the airline offer something without eggs or something vegan for the vegetarian meal option. A lot of Indians are lacto-vegetarian, while some could be allergic to eggs/dairy.

Crew were nice, food was good. Boarding was horrendous. We were driven around the airport in a bus forced to climb a long flight of very steep stairs with no adequate handrails to board the plane . In many many years of flying to the US I have never been required to do this . There was no assistance for those needing help getting up the stairs to the plane. A fellow passenger helped me. No idea how other elderly, physically limited passengers or those with young children managed . It was a full flight with crowds trying to get up the stairs. It was an accident waiting to happen.

Horrible, the plane is just old and junky...Filthy restroom, seat was as hard as rock. The food, mystery side dish, inedible..geez..just Horrible. Never flying BA again

the service on Business class should be improved to be at par with industry leaders like Cathay Pacific and Singapore AIrlines. A lot of room for improvement.

Old wear of seats, uncomfortable, hard to seat. Entertainment equipment malfunctioning, sound system bad, old hardware. All together made my mind not to use BA going forward.
