I am arriving at CDG Airport from the U.S. at Terminal 2E on Air France. I have a layover of 1 hr. & 25 minutes to catch an Air France flight to Nice at Terminal 2F. Is this enough time to go through customs & security, assuming that my flight is on time? The next flight is not for almost 4 hours. I know it will be close but my flights are not until June and I am debating on changing to the later flight.
