I bought a AF ticket and the ticket shows my sky miles number. MAA-CDG-ATL Return ticket in Z class. But I can’t find my booking in Delta website or fly delta app. Called Delta and they are saying the ticket does not have skymiles number. Called AF and they say ticket already has my skymiles number. How do I resolve this issue? Thanks

Update: when I search for the flights, I can find the same flights listed in delta website, but no DL number, just AF numbers. Does this means this is not a delta marketed flight?
