I don't quite understand. With your example (UA511), these segments/flight numbers aren't in the air at the same time, nor do they share the same DEP and ARR city. Well, I see in the rest of your description it IS possible to have them up in the air at the same time under those circumstances. INTERESTING....didn't know.
