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

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.

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.

Ad experience - been flying many years with them but they are losing out to other carriers with their service and bagage / seating policy. My 2 12-yo kids were not placed with the parent. Absurdity.

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.

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.

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

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!

Nice to fly out of Orly smaller easier to navigate airport. Being able to receive boarding pass well in advance of trip was comforting to know all travel was in order.

Liked. The check-in was pretty quick as they had 5 desks working.

Generally a good experience except for boarding in Naples on the flight back to London. We were all standing around for at least 20 minutes maybe longer as there was no seating.

Seats, WC,sizes for today's generation adults, and if technical problems arise a complimentary coffee, water nice for waiting one hours, the rest is perfect (pilot and cabin crew)

Boarding was smooth and quick. Flight departed on time. Equally evacuation upon landing was from both the front door and the back doors. Bags were on the conveyor belts before I got there. Excellent service.

The terminals are far away, be prepared to walk. Also, You climb stairs to the plane since there are no aero bridges. Boarding was haphazard not in multiple groups, so stand in line early. Hard to find place to stow cabin baggage if you are behind in the line. You can purchase food on the plane. There are vegetarian options.

First -the flight was late - more than two hours Second, not even a bottle of water at bord to give for free for this inconvenience. Three-at landing ive realised that I've lost one of my ear plug headphones and been very desperate to find it with my torch, the crew not helped at all more than that they asked to leave the plane as everyone did before me. This was the last flight from that day- extra 5 min for me with a bit of help from crew - would have bring a super review. I guess this days humanity disappeared!

I got caught using a stolen credit card number. Michelle Siziba is my name Nice to London Gatwick on 7/31/25.

Not happy with price of luggage or that we had no choice but to pay whether cabin or hold. I didn't book seats but this is unnecessary extra money along with suitcase

We accidentally purchased twice the bags we needed. Our fault, but the ticket was not clear to us, and it asked us to purchase bags at checkin. When we notified them to get credit back at the airport, they said to contact customer service. We flew the flight and then contracted customer service. They said no credits after the flight has flown. Not customer service oriented at all. They know we didn’t check that many bags and kept our money for a service they did not provide. Be aware and very careful of what you are purchasing from them because they will not make it right if there is an error.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

Boarding was quick and easy, the flight was on time. Food and water were extra costs.

Efficiency of staff, and comfort and cleanliness of aircraft was all great. Maybe a hot drink without payment at that time in the morning would be good!

The plane was late (as was my flight out from Birmingham the day before)

The flight was delayed by an hour. Made the connection uncomfortably tight.

I wasn’t allowed to board with my children. I was charged outrageous costs for basic carry on size luggage. The entertainment screens were outdated and not user friendly.

When we went to the lounge they told us to go into the main lounge and not the full business class section, later they told me that Lufthansa wont pay the full fee to alloq the business class passengers entry to the nicer sectikn where all the other airlines nusiness class passengers go into. Very poor arrangement.

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

Crew were friendly and very helpful Plane was clean and the legroom is standard. Overall a good flight, no complaints.
