I am in the same boat with you, I don't get it why having different last names in a marriage should make a difference

Hmm... but my wife does have the same address?

Maybe folks at the GS desk are more sensible. And what really gets me is that I always pay the taxes with a credit card with my name on it! They're happy to let me
buy a ticket with that same card for her. If you're really worried about fraud, you'd think they'd be more concerned with the cold, hard cash than the miles...
