Subject: Re: Passport Control at Charles DeGaulle Airport
Indeed, France clears people by checking their passports at CDG before letting them take their connecting flights in my experience. it's probably much easier for them to funnel every passenger arriving on flights from non-Schengen countries through a few passport checkpoints than to maintain secured paths for them from, potentially, every arrival point to the departure gate of every possible connection.

People didn't seem to be taking more than their carry-ons with them in CDG so the customs question remains a mistery (I only take carry-on luggage for every trip). it may happen when you arrive to your final destination.
