Hi,

We have a family trip (me, my husband and our young daughter) to Paris in May, and while we all fly in together we unfortunately won't be flying out together on the same flight out of Charles de Gaulle (CDG) airport.

My husband our daughter will fly back with Air Canada out of Terminal 2B. Whereas I will be flying out 1h45min later with Air France out of Terminal 2E.

Our questions are:
1) Can we all go together to Terminal 2B so I can be with them right up until their boarding, and then head over to Terminal 2E myself --and will my 1h45min be enough time? (I hear mixed frustrating stories about CDG travel)
2) Husband and daughter have Business Class tickets with Air Canada, whereas mine are for a shorter local flight with Air France so currently in Economy --will that slow down our whole experience substantially? (If so, far enough ahead that I can upgrade the Air France ones to Business for this short trip to all be in the same lines together)

Thanks for any insight you all can offer. Just want the end of the trip to be nice (as possible), and not too CDG chaotic
