Where can I find information about the flight number?

The flight number consists of a two-digit airline code and a maximum of 4 digits. The airline code is already prefilled according to your selection. Please only enter the digits you see in the Flight field next to the airline code. So-called codeshare agreements can lead to differences between the flight and the operating carrier. The operating carrier can be found on the passenger receipt under the information "operated by". If the airline code is different from the operating carrier, please select the airline that is the operating airline for that partner. If you do not know the flight number, please enter the numbers shown on the boarding pass or passenger receipt, next to the airline code.
