I think I previously submitted my feedback about flight lead Katherine in a different field by mistake. Please see those comments. Comments for Hyd to AMS are it was good. The flight lead and service met expectations for satisfactory high quality service but the flight lead did not stand out as exceptional as did the leads on the other two flights so I don’t remember anything specific one way or the other besides the fact I was satisfied.

Had to cancel and rebook, KLM connection was cancelled prior to departure, ended up flying to Munich on non-Delta carrier.

The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

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.

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!

Cabin crew were excellent, very proffesional, polite and friendly, in flight snack was underwhelming, a packet of cheese biscuits, im sure KLM could run to a sandwich!

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

The baggage service at Malpensa was the worst ever. We wanted for over an hour without any information, they broke my suitcase, and the services of the local luggage services company was below any usual services level of a KLM partner.

All and all pretty good. It’s crowded but that is what flying is all about. But no complaints otherwise.

Never made it to Lufthansa because of Air Canadas negligence.

Perfect airline, super friendly, great service, tasty food. Would fly again.

Boarding and flight update was fantastic as I experienced about a 10-15 delayed for both flights. The food served onboard was great; the service of the flight attendants was excellent.

Complete mess. Our reservation was mistakenly cancelled. After almost missing the connection and walking all over the Munich airport, the Service desk got involved and we were run to our flight. Not all 4 of us in Business and not seated together as originally booked. This was the worst treatment I have ever had. And I travel a lot. 1K million miler.

The flight was delayed more than 1.5 hours. Phone calls to united did not satisfy our need to get to Chicago to met family for fight to europe. I was told the flight was booked thru luftansa and united could not make adjustments. When call luftansa they were unaware of the significant delay on the united flight out of mci. They would not authorize a flight change. We went to the airport, as if we would be flying as scheduled, United checked us in, as if our flight would leave as scheduled. We took our bag to be checked to the baggage drop and the agent their confirmed our flight was significantly delayed. She worked for 30 min to get us on another flight. We ended up flying to Denver then to Munich. The rest of the family that flew to Chicago for our meet up and flight to Europe ended up flying to Munich alone. We meet up in Munich for our last leg to luxembourg. In luxembourg we learned on bag was scheduled on our delayed flight. The flight was canceled and we did not receive the bag in lux. We filed a lost back claim. Now 3 days later we STILL do not have the bag. It is apparently in luxembourg and they maybe tried to deliver, however the names on the door of the air b&b do not match the name on the baggage claim so the French speaking delivery person called no one could understand him so he took the bag and left. My brother, traveling with me under a different reservation , has been without essentials for 3 days. One or all of us has stayed "home" each day waiting on the bag. Today was my turn. Delivery window was 10:30 to 2:30. No attempt to knock or ring bell. After the hang up call, my brother called me and told me to check the door. There was nothing there. No sign of attempted delivery, no delivery man, nothing. Being unable to change clothes and having family members take turns waiting on a bag that never comes has ruined this family vacation. Thanks United/Luftansa

The flight left an hour late and no explanation. Food was basically a few snacks out of bags and tiny cup of soda. Crew was pretty friendly.

The The check in process was terrible on both ends. It was not clear if we should use the United, Lufthansa, or Aragrant number. It took over an hour to check in on the front end – and then at return the Lufthansa online check in failed multiple times and only after two calls to their phone number could we accomplish the task. The link to the Kayak site provided no access for check in. This difficulty and ambiguity on both ends will affect our interest in using Kayak for foreign travel in the future.

Lufhtansa has and can do better. The food was inedible. No individual light for reading.

You lost my bag then waiting on the phone for 30 mins for customer service just to be directed to call another number

Boarding staff, crew and food needs a lot of improvement!! It was awful Aircraft was old with minimal legspace
