A two-hour layover at Paris Charles de Gaulle (CDG) is generally considered the minimum "safe" window for a connection, but it can be extremely tight depending on your specific terminals. If you are flying on a single ticket with Air France and staying within Terminal 2 (e.g., 2E to 2F), two hours is usually sufficient as long as your first flight is on time. However, CDG is a massive, sprawling airport known for its long walking distances, internal shuttle trains ("Navette"), and frequently congested security and passport control queues. If you are arriving from outside the Schengen Area (like the US) and connecting to a European destination, you must clear immigration, which can easily take 45–60 minutes during peak hours. In 2026, experts recommend at least 3 hours if you are changing terminal complexes or flying on separate tickets, as CDG is notoriously difficult to navigate quickly, and a 15-minute flight delay can easily cause you to miss a two-hour connection.
