RE: Charles De Gaulle

Terminals at CDG are a euphanism.
AF have all of Terminal 2, that’s Hall A, Hall B, Hall C, Hall D and Hall F.

the TGV station is situated between terminals D/C and F, under the Sheraton Hotel. The RER station is at the same place (From Terminal 1, you have to take a bus). The Metro dosen’t go as far as Roissy from the City Centre, but with an RER ticket you can change as many times as you want in town.

Halls A-D are small (5 piers each), and pretty boring, but F is modern, spacious, and has a lot of big windows to see out of.

And a word of advice – take gate announcements with a pinch of salt, I got conflicting gate details from different screens.
