I am arriving at CDG on UA and am considering taking Air France from CDG to Montpellier. In the past, I have had bad experiences at CDG trying to check in for Air France flights with bags to check when I can't check the bags all the way through to my destination. Now that everyone is in Terminal 2, I would hope that it would be easier to retrieve my bags from UA and check in on Air France.

Can someone with recent experience there give me some idea about what to expect? I would particularly appreciate any advice about do's and dont's to facilitate the process.
