Our flight delayed, due to the incoming flight arriving late from Paris. AF caused us to miss our connecting flight, also booked through Air France directly. They couldn't accommodate us until later that night, and we had to be in AMS earlier than that. They won't do anything else to help us and wanted to charge us more money to rebook us too. Not great service, since it was all their fault.

The flight crew was exceptionally friendly and helpful. Also the seats were comfortable and roomier than many other airlines.

Our flight crew were terrific. And they handle a difficult passenger with finesse.

Excellent, Lima to Paris. But Paris to Amsterdam, delayed, missed my flight and KLM treated its missed flights passengers very badly, terribly bad. No hotel accommodation given. Passengers were told to find their own hotel accommodation and claim at reasonable rate and left the booth and literally with armed Police Officers listening to passengers complains. For three hours, after moving by Uber from hotel to hotel and calling and booking online, no hotel was available. I had to return to the airport and seat/sleep on the benches, suffering the cold, and rats running around until my new allocated flight the next day. It was the most terrible KLM treatment even seen and being a Business Class passenger. Still mentally suffering to date as a result.

It was not Air France but Air Europa. But confusion over our checked luggage. Whether it was checked all the way to Tenerife or not. It was not. Had to line up again in Departures. At least our Sky Priority was honoured. Flight was fine.

The plane was old Only 3 bathrooms available for economy The entertainment was old and the selection was poor

Very good crew. Food service above average. Seats very small for a 12 hours flight.

The check in was horrible. I stood in line for 1 hour to check in with an Air France ticket. Then I was told I had to go to Delta counter onstead to check in instead. It made no sense.

Business class in the second leg - CDG-EVN was a disaster.

I have used Air France and KLM many times it will help if they change their menu's feel like it's been the same for years!!!, Especially the breakfast. Overall the flight was good and enjoyable.
