Thanks guys for all the opinions. I did go through UR and got the 2x points through Travelocity. It's a business trip so I know the times won't change and there were few options that worked for her anyway for this particular conference, so I'm not worried about the perceived lack of flexibility.

Since it's a business expense I wouldn't consider asking to put it on my CC, but I figure to go through a portal isn't such a big deal. I do that when I buy office supplies too - order stuff on Staples using her CC but go through whatever portal du jour that gives me the most points/miles. She knows I do it and she doesn't care - she couldn't care less about miles or points. I've tried three times to get her to sign up for UR cards, but she hasn't conceded yet.

Also - she owns her own business, so there is really no "corporate" to worry about other than her!
