In October we are travelling from Wisconsin to Naples through CDG. Delta sent me an email that my flights have had a schedule change such that we might not make our connection at CDG to Naples. We arrive from Wisconsin at 8am at CDG at Terminal 2C and our flight to Naples leaves 9:15am from terminal 2D.
My question is twofold: can you get from Terminal 2C to 2D without having to go through security a 2nd time and also, is there an immigration or customs process we must go through while deplaning at CDG before boarding our flight to Naples assuming we don't leave the airport or security area?
BTW, Delta told us to hang tight because there will likely be another schedule change before October, but who knows if a future schedule change will make our layover time longer or shorter?
