Try to upgrade. The international facilities at the airport post security are very busy and unpleasant. Try to book into a lounge if you can although you may need to upgrade to business class. the American Airlines lounge is pay on the day but it costs $150 per person.

It was really nice experience by flying this klm flight.I personally recommend everyone to please try this klm flight

It was really nice journey i personally recommend klm flight

The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

Empty seats next to me - wish it had been for a longer flight!!

I’m grateful for the KLM Air France shuttle bus service to Ottawa. However due to construction and other issues related to the chaotic Uber pickup system at YUL, it’s a challenge to find the Kelios bus service to Ottawa. The signs are not clear or even available. No staff to guide passengers. It’s a stressful experience.

Flight was on time, staff are friendly and helpful onboard.

Terrible last row seats many seats available but no offer to move to better seat

Delay on my previous leg, had to run to catch my flight. But that happens. Overall ok.

Delay and had to run between flight to get my connection due to this delay but besides that the overall experience was ok. I arrived with just an hour of delay.

They forgot to serve food and the crew was very unfriendly. Never experienced such a bad KLM flight. Usually fly from Toronto. New York was different.

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

Food has been disappointing in both legs of flight to india

Great staff great experience, made a 2 hour delay very bearable

Great staff, great experience, made a 2 hour delay very bearable

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

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

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

Great crew - old style upper class seats on the older fleet now feels dated

The entertainment could have been better, better choice / better headphones, but overall very satisfied

The friendly staff. They kept time. Was suprised to get some drinks.

We did not even get on this flight as the plane never left London. I missed the email that was sent mid morning USA time, so we were not aware the flight was cancelled. There was absolutely no help from the staff at the Norse check in gates, we were told to take a picture of the board they were holding up, to try and claim our money back. We were told to book our own flights to London which ended up costing $10000 due to the last minute. And now we have to return to Miami in 2 weeks. I am not holding my breath about getting on board for that flight either.

Great experience. The flight was smooth with very little turbulence. We were in premium classic, so lots of leg room.

Didn’t know you had to pay for earbuds and food on flight. Sounds awesome and better way to not waste food or items. Comfort of flight is was amazing other than that

Unexpectedly was surprised with the space on flight in economy and the price.

I was not expecting having to pay for headphones, water and basic food in a 9 hours flight. Price for this flight was as high as any other, still I had to pay 4 lbs for a can of sprite. On top of that flight attendance gave a bothered look when I asked her for some ice for my soda. She reluctantly when to get it, brought me literally 3 cubes and walked away without looking at me to avoid another request. I couldn’t believe it. She was soooo rude. I will never book on Norse again and I will let everyone I know about this. Unforgivable, very bad customer service.

Great crew. Customer support is pretty much non existent. I had 2 tickets that were not used, the flight was overbooked. I think I should have been reimbursed for the unused tickets.

The movies were super old. The crew did not offer WATER???? 5 hours os flight and did not get WATER? Norse is the worst company I ever used and never will use again.

Why call us to board if we’re going to be made to stand in the tunnel for 20 minutes. Really hard for people with little children. Plus it took me ages to check in because my seat in Premium was overbooked so I didn’t actually have a seat. I did end up receiving my seat in Premium but there was a lot of stress and confusion beforehand. Hope is it possible to overbook seats? Especially in Premium!

My flight to London from Philadelphia was cancelled due to weather.

Disliked having to wait a little longer to disembark from the plan when we landed in London

Food should be better quality. Video screens have poor resolution and the library of movies is poor. The other airlines are much better.

The trip was smooth but the crew were very abrupt, snatching things before finished and being quite snappy when asked questions.

My wife and I love to travel, so we fly a lot. We've already logged 381,075 miles and with practically every major airline. But this flight was very disappointing. It started off well, with no delays and a new plane. But when lunchtime approached, all that good impression was ruined. Instead of white tablecloths, we were offered small, dark placemats, which, as it turned out, were perfectly adequate for the food. All the food offered—and my wife and I only took fish, and the meat—was not just bad, it was downright disgusting and not heated enough. The same applies to the appetizers. This was the first time in many years of traveling that we've been offered such disgusting food.

Lost luggage stuck no clothes and no word after 2 days leaving on cruise no stuff or clothes

Don’t know they cancelled the flight day before I was to leave. They sent a email at 9:00 pm at night saying they cancelled. That is the smooth way to say we don’t want your business! I think they didn’t have enough people booking so they cancelled the flight! It’s all about the money anymore there is no honesty in business.

The flight was canceled 3 hours after original take off time

Pathetic check in experience at JFK. Everything is self check in. Not enough staff present to help with when the check in process or the kiosk gets stuck. Staff present not welcoming or pleasant at all. On the other hand the NY based flight crew was great. Courteous and friendly throughout the flight. Special meals leave a lot to be desired. Kids meals should be made available when kids are flying and same goes for special kids meals too.

Flight was full, and would have preferred an aisle seat, but due to getting a late ticket ,the seat I had was adequate. The flight crew were very help full and hard working. Food and drink were excellent for the 11hr flight. Overall I was pleased with flight, and would recommend British Airways again.

Very good staff members with sincere passion and responsibility in their job.

Very please with the seating that the Kayak staff booked for us!

Worth every penny to upgrade to BC. Treated and felt more like First Class

Good service, food and comfort in World Traveller Plus. Entertainment was poor - no wifi on the way out and barely working on the way back. Not a great choice of entertainment on the seat back tv.

They had us seating down for one hour just waiting on the plane

Flying with BA is always a good experience—even in economy class. It is better if in business and first class. Timely, breeze through security and timely connections

We waited at BOS at the gate for an hour and couldn’t get a drink or anything. Once in the air the service, food and ride was excellent.

My enetertainmnet screen was broken. Lost my bags. Almost missed my flight do to connection issues with (despite a request) ZERO help from crew. Food was edible. Potatoes pretty good even

The issue was not with BA it was with the link yoiu sent fopr booking the flight

Loved the boarding option from Business class lounge, experience on flight was excellent, plenty of good food choices
