As previous posters have said you do not need to recheck your bags, however don't hold your breath they'll be arriving at the same time you do. Seven of us flew DL FLL-CDG-MSP this fall with slightly over 2 hour layover in CDG yet none of our bags arrived. Received mine 36 hours later, just in time to unpack and repack for next trip. I would have preferred an additional 36 hours in Paris rather than my luggage.
