Pros: The crew was friendly and nice but not much help in dealing with the flight cancelation.
Cons: After a two hour delay at the gate and runway, our flight was canceled due to a mechanical malfunction. After we disembarked we stood in line for over an hour to rebook for the next days flight home. Before making to the booking desk we were then sent to the KLM customer service desk where we were told we would get a hotel voucher and an airline over night kit and NO access to our luggage. After waiting in this line for another hour and a half we received our voucher and were told to catch a shuttle to our hotel and another hour wait for the standing room only, half our bus ride to a hotel. After five and a half hours we made to the hotel. The experience was awful and seemed like Delta/KLM had never dealt with a flight cancelation before. The entire process needs improvement and so many levels— one can't help feeling that the airlines just don't care about the customer experience.
