I don’t like that an equipment change caused my seat to change from 23A to 44A. The boarding was also delayed. The crew were excellent, however and very attentive. The food was not bad.

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.

3 hour delay but out of their control. App said I get vouchers but when I applied for them, they were nowhere to be found in my account

I bought business class tickets but the seats are exactly like economy with no comfort seats nor an empty seat next to me provided. Very poor, low quality airline.

I don't understand the concept of paying to get your personal luggage onboard and then asked to check it in.... either sell the space or don't, its a hassle to carry those all through the airport just to make a check in at the last minute.

The food was great and the service and attitude was amazing!!

It was a great experience. The only thing I would have changed was that the bathrooms were never cleaned and they got very dirty.

Old airplanes small seats expensive tickets, not as expected overall and not comfortable according to the price

My experience was good overall, the quality of the food really decreased! There used to be a choice between meat and fish now it’s between chicken and pasta! In the choices of entertainment meditation has been added which is very good. Soft chair workout to improve blood circulation and avoid phlebitis should be added.
