Howdy! Just came from the partner area of Thrifty's site. Pleasantly surprised to see the following:

America West FlightFund – FlightFund
membersmembers can earn QUADRUPLE miles
**that’s 1000 miles per rental
transaction instead of the usual 250
miles per rental transaction** between
February 1, 2003 and December 31, 2003
when renting from Thrifty. Cars must be
picked up during the promotional dates.
Advance reservations must be booked at
thrifty.com using PC code AWI3 to receive
this offer. Offer not valid with other
discounts or promotions.

Just in time for my PHX rental tomorrow morning. Wow!
