I appreciate that KLM was proactive in informing me of the 2 hour delay which enabled me to replan my travel. It was a bit stressful not knowing whether my connection from Montreal to Ottawa was happening. But the ground and air crew did a good job at comforting and assuring me.

I appreciate that KLM was proactive in informing me of the 2 hour delay which enabled me to replan my travel. It was a bit stressful not knowing whether my connection from Montreal to Ottawa was happening. But the ground and air crew did a good job at comforting and assuring me.

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

They only had vegetarian food left on the flight which I wasn’t happy about. I didn’t get any food to eat at all.

Overall very poor. Flight was disorganised, staff were rude and this is my second experience with KLM that I've had baggage go missing. It feels like, if you are an economy customer, KLM staff do not show you any care. I shall never fly with KLM again. Worst airline in Europe

Great boarding, great short flight but no entertainment whatsoever and no wifi. Prepare to disembark by a staircase.

Great boarding, great short flight but no entertainment whatsoever. It was supposed to have wifi but that did not work.

Good flight with KLM, friendly staff. Food was good, had much worse on other airlines. Selection of drinks also good enough for us. Entertainment was also good. The economy seats are ok and that’s it. For a 12 hour flight I think a little more comfort in the economy seats in pitch and softness would be highly appreciated by the customers and can makte the difference.

There was fog in Amsterdam so many flights were delayed because of the weather. Air France knew that the flight would be delayed by two hours but still boarded the plane on time. Instead of letting the passengers wait at the gate we were crammed into the plane. It was uncomfortable. No refreshments were given. I couldn’t charge my devices onboard.

I tried to upgrade to premium economy anis seat online during the checkin process. The payment didn’t work due to a technical glitch on KLM’s website. I wasn’t able to change my seat unless I called Amsterdam. Since I was in Canada and there’s a time difference this wasn’t practical. So when I arrived early to Ottawa airport my seat wasn’t available and I could only get a middle seat in premium economy which isn’t great. These middle seats are priced at the same rate as an aisle seat which makes no sense.

Overall flight was fantastic.i really enjoy the whole journey .

Little more legroom would have been nice. But it's a very short flight, so it was fine really.

Short flight, some waiting to board, but no issues and no frills.

No staff at the gate and the flights were not posted on the board so we missed our flight. Horrible experience. Be VERY careful flying Norwegian. Super limited ability to communicate with their slim staffing and restricted hours.

Tickets were cheap but it says no where that food was not included, I travel Austrian, Swiss and Turkish airlines all the time always food is included, never flew Norwegian again

Pros: "Nothing,except I got to my destination safely"
Cons: "Everything.They don’t ever offer you WATER in a 10 hour flight!! Check in crew rude. Attends dismissive to rude."

They cancelled our flight home less than 24 hours before it was supposed to leave. It partially ruined our last day because I was on the phone trying to get 5 people home and the stress that it causes. We still arrived at the airport with no definite flight plans. The actual flight was good but my kids really misses the kids meals I had ordered for them which obviously didn’t make it to the new flight.

Very helpful in getting us off the plane first to make a tight connection.

Very unfriendly approach to me when you rescheduled my return flight due to your delay. No help to address my health concerns because I am diabetics and had orthopedic problems. No clear explanation where to clear customs. I had poor customer service

The seats were really cramped. The high backs on the chairs made you feel claustrophobic.

The flight got canceled and you just send an email in the middle of the night and no solution to how to get on the next flight or provide other solutions.

You cost me my time and did not compensate properly. Gfy.

Missed a connecting flight and SAS was at fault. I was awarded a $20 voucher in exchange for 8 hours of my time? Gfy.

Seat was lumpier than I’ve ever remembered it to be although comfortable when tilted back. I don’t recall being that hungry after being served food from SAS before. Flight attendant on the second flight to Aalborg seemed to be having a bad day.

Please see my comments for the flight from Chicago to Copenhagen

All flights were on time! The crew was nice and polite Thank you. Food was awful. They give you terrible pasta or rice dish and make you pay for chicken if you’d like meat. When I asked for water with my tea, they told me, I’d have to pay 3 euros for water. Restrooms were filthy half way through the flight.
