I'm a 1P-soon-to-be-1K on UA and have the UA MP Visa. My wife, feorlen, is a Gold VIP with Hilton and has the Hilton Hhonors Amex. Most of the time it works out rather nicely with one of us collecting miles and the other collecting hotel points. We both charge our own stuff on our respective cards and collect the points/miles for our purchases.

Today we had a minor good-natured scuffle over who was going to pick up the bill for lunch.

My parents are in town for the Thanksgiving Holiday, having flown out from IAD earlier this past week.

We took them out to the new Academy of Sciences @ Golden Gate Park and booked a table at the Moss Room in the basement for lunch(Which I'd recommend if you can afford it. It's not ridiculously expensive, but it's not the main cafe upstairs either).

At the end of a good meal, our waiter came by and dropped off the check. I snatched it up quickly, mostly to prevent my Dad from trying to pay for it(He paid for dinner yesterday) and immediately threw down my MP Visa. feorlen's Amex hit the table simultaneously and we both looked at each other, trying to look determined but really just about this far >.< from cracking up.

"You just hand that check over right now there Mr. 'Dillo" feorlen said.
I could see by the look on her face that I wasn't going to win this one , so I passed it over, chuckled and pocketed my MPV card.

I'm curious as to whether other FT couples have similar "problems" ?
Do you have just one card or do you each have your own ?

For ourselves, I'd say we split things up pretty evenly between the two cards.
