Just saw this thread. Here is an updated luggage experience flying DL MSP-CDG and then onward on AF CDG-EVN. DL allows non-revs 2 pieces each so the two of us had 4 pieces between us. We have flown this route several times over the past 3 years and never had a problem getting all 4 pieces to our destination and never had a charge for extra luggage UNTIL this year! In March of this year (2015) when we got to the transfer desk in CDG, they said AF only allows 1 piece each even though DL allows 2 each. Therefore we were charged for 2 pieces of luggage AND THEN (this is second time it's happened with this route) only 2 pieces made it to EVN, we waited a couple days for the remaining 2 pieces to catch up to us. Maybe we got lucky all those other times traveling and this time got busted with 2 pieces each.

I wondered if AF does this with all their connecting DL non-revs/ZED fare passengers? Anyone else have this experience?
