I booked a car rental (Thrifty) through Capital One Travel.

Question -- how can I look up my rental on the Thrifty site? I can't find a Thrifty reservation number on my reservation details from Capital One Travel. And the Capital One reservation number doesn't work. I don't have a Thrifty Rewards number, so I didn't put it in at the time of reservation.

Related Question - does Capital One Venture X give you any special status at Thrifty (as it does at Hertz)? If so, how do I ensure my rental is upgraded to that status?

Thanks
