Booking Basic Fare on Delta for AF Operating Flights
I apologize if this has been covered; my obligatory searches couldn't find the answer. I've got Delta vouchers that I'm considering using and thus need to book on Delta.com. I'm looking at flights that are on AF metal. There is a $100 difference between Basic Economy and Main Economy. I understand what the differences are on Delta flights between the two, but what is the difference if the flights are operating on Air France? Would I be able to select seats ahead of time, for instance (with or without a fee?) Would I receive a free checked bag (on Delta metal, clearly not, but AF)?
Thanks.
