What matters for getting 300%/60% is that it's AF *marketed* (at least for after Jan 1). to my reading it doesn't matter who sells you the ticket as long as it has a AF flight number on your ticket.
I bought from AF because I couldn't (quickly enough) get Delta to give me first class and/or AF flight numbers.
