Paris is served by two airports : Orly in the south and Roissy (Charles-de-Gaulle) in the north.
Most American flights now arrive at the expanding Roissy Airport.
Orly-Ouest terminal is monopolized by internal French flights. There are no airport taxes to be paid on arrival or departure.
Both Orly and Roissy have extensive international airline facilities, including car rental, duty-free shops, restaurants, post offices, hotels in the proximity, and ground transportation into the city center. Air France and airport staff are, on the whole, helpful, and they always speak English.
