The cost would be the same.
JFK-CDG is 3,635 miles, so RT on AF would be 3,635*2*0.4=2,908. The better MQD would therefore depend on whether the fare is more or less than $2,908.
Who do I call in case of schedule changes or other issues? Given DL phone problems, that might be an advantage of booking through AF if the marketing carrier is the contact. OTOH, a DL voucher would be much better for me than an AF voucher, pushing me towards DL, if those that becomes applicable..
