I'm looking at this fly with Air France from ORD to ARN and return (via DTW, CDG) from ARN to CHS (CDG, ATL)

Since I have the Delta Amex card, if I book this flight with Air France light eco ticket, do I get any benefit (Free checked bag, early boarding) if the flight is operated by DL?

ORD to ARN trip is all operated by DL

from ATL to CHS is also operated by DL.

I would rather to book this thru DL, but they do not offer light ticket on their website
