She flies U.S. Airways into Paris CDG. She then flies Air France from Paris CDG (it says 2F (?)) to Nice.
First, what does that Paris C. Gaulle 2F mean on her ticket?
Second, is the change from one airline to another at all complicated? Terminals? Buildings? Shuttles?
Third, how much time does she need to do the transfer from one to another?
I would appreciate all help you could give. This is her first solo flight, it is international, she will be traveling for a long time and I want to help make it as smooth as possible.
Many thanks.
