Update 2: Remember to give Hertz your mileage number when picking up the car!
Here are some participating programs:
AA-1 mile per dollar spent.
Airtran-1 Credit for 5+day rentals.
Cathay Pacific-500 Miles per rental.
Continental-500 Miles for 5+day rentals.
Delta-500 Miles for 5+day rentals.
Frontier-500 Miles for 5+day rentals.
United-500 Miles for 5+day rentals.
USAirways-500 Miles for 5+day rentals.
Update: I made a reservation on orbitz for 99 days (it doesn’t cost anything to reserve) and when I plug in my confirmation at Hertz.com it shows the $3 price(even though you can’t reserve it for $3 on Hertz.com) and that I have a “VW Beetle – Fun Collection or Similar” rented for the period.
Orbitz Booking Linky
Minimum rental is 5 days, maximum rental is 99 days.
A 99 day rental comes out to about $600 including all taxes.
The car has manual transmission.
Works easily for all of the dates that I tried…
