Hi,
My wife and son (who is 6 months old) are flying CVG-CDG-DXB on Jul 22 08. Since infants get cranky in long flights, I booked them via paris. But after reading about "not so good transit experience in CDG", I regret, I should have booked them ATL-DXB direct flight. Anyways

They are flying

22JUL DELTA 44
LV CINCINNATI 730P
AR PARIS-DEGAUL 955A

23JUL AIR FRANCE 526
LV PARIS-DEGAUL 115P
AR DUBAI 955P

They have about 3 hrs of layover in CDG. Please post if you know or have similar experience.

1. What terminals Delta 44 arives at and AIR FRANCE 526 departs from ?
2. What will be easient way to change terminal if they have to? (Travelling with infant)
3. Would they have to go through immigration/security while changing terminals ?
4. What are options in case flight is cancelled.
3. Any other useful information

Thanks in advance
