Charles de Gaulle Airport has three terminals: Terminal 1 is the oldest and situated opposite to Terminal 3; Terminal 2 is located at another side with 7 sub-terminal buildings (2A to 2G). Terminal 2 was originally built exclusively for Air France; since then it has been expanded significantly and now also hosts other airlines. Terminals 2A to 2F are interconnected by elevated and situated next to each other. Terminal 2G is a satellite building connected by shuttle bus.
Terminal 3 hosts charter and low-cost airlines. The CDGVAL light-rail shuttle connects Terminal 2 to Terminals 1/3 and their parking lots. Refer to Ground Transportation below for inter-terminal transfers and transport to central Paris.
Terminal 1 : The first terminal, designed by Paul Andreu, was built in the image of an octopus. It consists of a circular terminal building which houses key functions such as check-in counters and baggage claim conveyors. Seven satellites with boarding gates are connected to the central building by underground walkways.
Terminal 2 is spread across seven sub-terminals: 2A to 2G. Terminals 2A to 2F are connected by inter-terminal walkways, but Terminal 2G is a satellite building 800 m (0.5 mi). Terminal 2G can only be accessed by shuttle bus from Terminals 1, 2A to 2F and 3. The CDGVAL inter-terminal shuttle train, Paris RER Regional-Express and high-speed TGV rail station, Aéroport Charles de Gaulle 2 TGV, is located within the Terminal 2 complex and between 2C and 2E (on one side) or 2D and 2F (on the opposite side).
