Here is some news on this one:
A part of the article from the DL's news web site:
Passengers traveling on Delta or Air France qualifying flights
(a qualifying flight is one Delta or Air France coded flight taken
with the purchase of a fare that is eligible for frequent flyer
mileage credit) will earn base miles and segments which will count
toward Delta’s SkyMiles Medallion status. Additionally, SkyMiles may
be accrued on all Air France coded flights worldwide and redeemed on
all Air France operated flights.
