Our flight to Nice is on 11/2 and it is now at 11 AM.

Originally we had approx 3 hours between our Continental flight and the AF flight. But I checked and that flight does not exist anymore and they put us on one that gives us 1 hour 50 minutes connecting time. I am wondering if that is sort of tight and I should ask to be moved to the next AF flight? That one will give us 4 hrs connecting time. It sounds like a lot but if our flight from the states is delayed it won't be that much . Plus, don't we have to do immigration in CDG?

Anybody has connected in CDG that can shed some light?
