Agree with other posters. Used to live in France and had to connect through/fly out of CDG quite a few times. Avoid if at all possible. Very low concept of customer service. No comparison whatsoever with LH.
As mentioned, be very suspicious of any transfer of less than an hour and any hope of seeing your baggage arrive on the carousel at final destination. If you end up with a tight connection, forget it, and you will be harried out of the plane by ground staff, piled in a van and driven to the other plane. Your bags won't follow you.
CDG has expensive, poor food (unless can get in a lounge), involves miles of walking, has virtually no cashpoints, public side seating and is hugely confusing. There is a shuttle train now between terminals, but this used to take 20-45 mins or more, depending on which one. The place is 1/5 the size of Paris itself. Oh, and taxis drivers won't drive you anywhere unless they can get 30euro + out of you.
And this is without strikes or security alerts.....
Routinely voted one of the worst airports in the world. With AF not the world's favourite airlines either.
Real shame, because Orly is an old school, lovely place to fly out of, near Paris, friendly taxi drivers and staff, no crowds, no fuss and a whole different atmosphere.
