I booked the flight on KLM because everyone said either KLM or Lufthansa. I booked the cat and it was confirmed on the booking.

Thanks for the good tip, will make photocopies of the documents, I have the vaccination records with me. I am not sure about the water bowl, maybe a 1.5 L water bottle that I can cut in half and fill with water? most water bowls are short and wont carry enough water in them. I think the crate itself has a water compartment at the top that I can use.

So I will get the cat with the luggage, do you know if there is a hold on the cat or I just take her and walk out with it?

Thanks again for all your help
