Both Orly and CDG airports are serviced by RER B (blue on the map). From
Orly you have to take the monorail to get to the Antony station; CDG has
direct service.
When in RER B, exit the train at Chatelet-Les Halles (some RER trains do
not stop at every station but all trains will stop there).
At Chatelet-Les Halles connect to RER A direction Cergy - Poissy -
Saint-Germain en Laye (red on the map, going west).
Exit RER A at the Charles de Gaulle Etoile station (do not confuse with
Charles de Gaulle airport). It's the second stop from Chatelet-Les
Halles.
At Etoile connect to Metro line 1 direction La Defense (yellow on the
map).
Exit Metro Line 1 at Porte Maillot. It's the second stop from Etoile.
As an alternative note that you can connect to Metro line 1 at
Chatelet-Les Halles directly from RER B, but the connection tunnel is
1/2 mile long and 1 mile when you're in a rush :-) and there are 9
stops.
