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.

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.

The immigration hall in Amsterdam was understaffed, so passport checking was slower than it should be for a major airport. They need to get the automatic readers up and running for non EU passport holders. Waiting in line after a long flight feels a bit abusive.

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 baggage drop-off in Stuttgart is bad: after online check-in you cannot use the automated baggage drop off as indicated on the website. You can use the terminals but have to cue to 1 of three open and slowly working counters to drop the bags. took about 45 minutes wait time.

My flight was delayed by 6 hours then I missed BOTH of my connecting flights, I then had to stay in the AIRPORT at JFK because soooooo many people also suffered from missing flights and there was no hotels available. I would like to be compensated for this experience! I had to stay in the airport for over 16 hours!

The service was great. However the lounge only gets passing grade

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.

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).

It was great. Enough space and room for legs . Great service to.

Well unfortunately our connecting was cancelled and next flight delayed. Was in airport 9 hours. Flight itself was good. I’m sure it was a FAA problem.

The flat beds. Other than that, the place was not clean.

No WiFi working on either flight. No leg room at all, the seat in front of me left dents in my knees. If I put the tray down, it was so low it was propped up by my knees. (I’m only 182.9 cm) I’m usually cool on planes, but the planes were both hot during taxi and take-off.

Why don't they board from the back of the plane to the front. We have to move by all the people and their luggage to get to the seats.

Everything excellent except for bag drop off. We started at the D area and that was so slow that it was eventually closed just as we were about to go to a station. We then went to F. We got one suitcase checked and then the screen showed that the station was no longer operable. There were long lines everywhere so we had to ask if we could butt in to the next station to finish. Again, this was the only incident, otherwise it was an excellent flying experience

Flight was delayed but my previous flight was as well so It worked to my advantage. This was my first time in first class. I don't think they ever stopped feeding us. The seating area was very spacious and comfortable. The attendants were wonderful, warm, friendly and very personable.

horrible! after going through hell and back to get a flight home after my flights got cancelled I also had a delay of 2hrs stuck inside the plane because of some technological problem.

Not so good with their baggage handling as they damaged one of my check in luggage
