As of April 2015, FastPark & Relax offers a rewards program rather than coupons. The Fast Park collection of brands has a program called Relax for Rewards in which travelers can enroll to earn points redeemable for free parking.
Fast Park is an off-site airport parking company with 17 facilities in 14 major airports across the United States, and FastPark & Relax is one of their brands. Travelers earn points on a rewards card when using it upon arrival and exit from any of the Fast Park facilities. Card activity is tracked, and the points are stored in an online account within 24 hours of exit. The card can also be used for ticketless entry and exit from the lot.
