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

At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.

Flight was ok but lack of communication cost me to literally beg to be put on another flight as connecting flight had departed

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.

Couldn’t get boarding pass in SLC even with help from a redcoat, so had to find a desk in AMS to get boarding pass. Technical problems so not sure why. Very inconvenient. The KLM app is not as user friendly as most apps. Also had to wait almost an hour on the tarmac for a fuel truck, which caused us to miss a connecting bus in LUX.

Over 1 Hr delay. No APU so no AC on ground. Plane was hot during boarding and then they closed the doors over 20 minutes before engine start so interior of plane was steamy hot and stuffy. Could have been helped by opening doors until ready to depart.

First of all we couldn’t check in online, then we learn at the airport we were on stand by for KLM’s mistake of overbooking. The seats were not comfy at all. Our luggage got lost.

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!

KLM remains a quality flag carrier airline which maintains its standards whilst all their competitors are lowering theirs.

Our first flight was delayed so we missed our connecting flight. However it was easy to book a later flight on their app.

The cramped seats are cruel and unusual punishment and may violate the Geneva code.

Big queues on arrival at airport despite having already checked in and only needed to drop bags off. Flight delayed which impacted on connecting flight.

The update about flights and the terminal changes information was great.

Check in was was and the agent was very friendly and helpful The lounge was nice...boarding was straight from the lounge Everything worked at our seats, and video entertainment was good ..food was mediocre

The flight was excellent in World Travellor plus. Well worth the extra money. Boarding at Phoenix was the usual poorly organized event. Very stressful.

Although business class, the seating was really cramped. The food was so so.

Not only were the aircrafts spacious, but the crew was friendly and efficient. I was so gracious for the included meals on the longer flight (8+ hours).

Smooth trip no turbulence which is always a bonus for me lol! In cattle class so an element of being a bit squished (but not as bad as other shorter haul airlines) smaller plane than the one we flew out on and entertainment system wasn’t as modern but still definitely passed the time. Lovely crew x

The check-in baggage belt was broken (which is understandable) but what was surprising is they would check you in, give a baggage tag and then you have to drag the baggage to a different counter at the end of airport. No vegetarian option in in-flight meal. British Airways remains the worst big name airlines and always my last option while booking.

Decrepit planes, poor business class layout designed to maximize revenue, no decent movie selection.
