A layover at Paris Charles de Gaulle (CDG) can be one of the most complex in the world, and you should ideally have a minimum of 90 minutes to 2 hours for a simple connection within the same terminal. If you are changing terminals (e.g., from Terminal 2E to Terminal 1), you should allow at least 3 hours. In early 2026, connection times have been significantly impacted by the full implementation of the EU's Entry/Exit System (EES), which requires non-EU citizens (including those from the US, UK, and Canada) to undergo biometric checks (facial scans and fingerprints). During peak periods, these border checks have resulted in queues of 1 to 3 hours. If your layover involves "self-transfer" (booking two separate tickets), you will need at least 4 to 5 hours to clear immigration, collect bags, and re-check them. Always check your arrival and departure terminals in advance, as CDG is spread over a massive area and requires the use of the "CDGVAL" shuttle train to move between many sections of the airport.
