MOW-AZ-ROM-DL-NYC. The fare is filed by DL but allows to have AZ-coded segments. RBD chart 1 information only applies to ROM-NYC segment which is DL coded. To find out what booking class should be used for AZ segment you go to RBD chart 2.
My reasons for wanting to know have nothing to do with caring about who owns the fare rules, collects the cash or plates the tickets. It is solely about being able to map what the operating carrier will report to the FF program of the crediting carrier based on the fare purchased from the marketing carrier. It could be on a single segment or part of a multi-segment PNR. It could be either of the two scenarios you describe above.
