I don't know. On my Ireland 3-day rental, no points ever posted. The guy I talked to asked me to mail a copy of rental agreement.

I didn't bother because it was only 3 pts.

The rental agreement number (2 letters and 7 numbers) NOT the reservation code is what Thrifty needs to find a reservation after it is finished. Send Thrifty.com the number, and see if you get credit.

...love to hear what happens regardless.
