The primary Star Alliance Lounge at Paris Charles de Gaulle (CDG) is located in Terminal 1. After passing through security, you should follow the signs for "Lounges" (Salons) located on the Level 10 (3rd floor) of the central building, specifically in the area between Satellites 4 and 5. The lounge is accessible via an elevator or stairs near the duty-free shops. It is divided into two sections: one for Business Class passengers and Star Alliance Gold members, and a separate First Class section. It is important to note that because CDG Terminal 1 has a unique "octopus" design with separate satellites, you should allow at least 15 minutes to travel from the lounge to your specific boarding gate. Access is granted to those flying on a Star Alliance member airline (such as United, Lufthansa, or Singapore Airlines) in a premium cabin or with eligible frequent flyer status.
