Klm start boarding while somw air issue in the plan

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.

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

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

You should not have to pay for WiFi in business class

Transfer at Amsterdam airport is very convenient and the airport is easy to navigate. Boarding was also quick and easy. Cabin crew were excellent and the meals were good, although lacking in options.

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. It was supposed to have wifi but that did not work.

…not even a power outlet. Nothing but uncomfortable seating with unhelpful staff.

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."

Standard short hop flight. No food, no entertainment. Just get in, get something to drink, and try to be as comfortable as you can for an hour.

Cancelled my flight. Only option had a layover in Italy. No compensation for the 4 extra hours of travel time. The travel agency, cheapflightfares, blamed Scandinavian airlines and said there was nothing they could do. Scandinavian airlines said since it was booked through a travel agency there was nothing they could do. The entire thing was incredibly frustrating. Never booking through kayak or with Scandinavian again.

Name change on tickets for a misspelled name was very hard to change

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.

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.
