How long will I need for a connecting flight – Sao Paulo to Rio?

H P asked:


I’m flying from Manchester to Paris (Air France), Paris to Sao Paulo (Air France) and then Sao Paulo to Rio (TAM). I’ve only got about 90 minutes to catch my connecting flight in Sao Paulo. Do you think that will be enough time? And will my luggage be automatically transferred?
Any advice much appreciated!
