That's pretty much what I do now anyway. It'll just be a matter of switching from the Chase UR family of cards to the BOA card(s).
Well, that's disappointing, but that companion pass would still be pretty cool for a quick trip down to the coast.
My family and I try to take one big trip a year and we try to use points/miles to pay for at least one of the big expenses for that. So, my husband and son have decided that they want to take a train trip. That sounds good to me, but I did have to talk them out of doing the New Orleans to LA...
