A very unpleasant experience! The fact that the flight number is written on the reservation means almost nothing. They don't wait for passengers on a delayed flight. Our flight was delayed two hours and the operator told us impassively that our bus had just left and there was nothing more that could be done. It was 01.00 in the morning...I was lucky to transfer with another company's bus, but that one was also at the limit. I do not recommend!
