+1 Often biz travelers can justify a FC or upgradeable Y fare when a red-eye is involved.

Flight numbers are another way. Non-NW flights are usually 800+.
Suprised you can't apply the same logic to DL.
It's not that the OP is unaware of a codeshare carrier. You missed the point. He is flying on DL metal and he want's to know if other airlines are codesharing on that DL flight. Looking for "operated by X" is not going to help him. He knows who the operator is. He wants to know who ELSE is selling tickets.
