Hey guys,
I know it is impossible to use the same callsign within European airspace at the same time.
In the USA it is a daily procedure to have one flightnumber for two flights. For example:
US 740 Chicago - Philadelphia
US 740 Philadelphia - Madrid
the second flight is the continous flight of the first one. If everything goes well both aircrafts would be in the air at the same time. But what happens if the first one is delayed with 3 hours or more? It is possible in the USA to have two aircrafts enroute with the same callsign?
I couldn't find anything in any manuals
