It's usually possible to transfer miles from one program to another but again, usually airlines charge you $$ to do so.
i think i follow, let me see if i do: if i buy two tickets on my credit card, one to be used by my girlfriend, the mileage gets tacked to her name? it doesn't matter who pays for the ticket, just who uses it?
then, when booking, is it better to use one card and one transaction, or two separate?
