In a targeted email that I received today (though the code will work for any MileagePlus member), United is offering TRIPLE MILES and 35% off rates when renting with HERTZ on rentals between now and September 30. Additionally Hertz is “giving away” Gold Memberships with this offer, though I have seen them give their Gold Status away quite easily on several occasions. In order to earn the TRIPLE MILES you must use CDP discount #62455 and PC#165896 and obviously you’ll need your Mileage Plus number as well.
This is the short cut to the reservation page for this promo.
The booking with the code for a 10% reduction must be made by 30 April, for travel up to May 2013. Unfortunately I doubt that I’ll be able to book within the next couple of weeks – wish it were valid longer!
@Anne – UA sometimes has a habit of renewing the codes, so keep checking for an update to the code/promo deadline!
