When you travel often, you learn pretty quickly that friends and family will only take you to the airport so often. Frequent travelers without convenient public transportation may find themselves parking in airport lots, which can easily end up costing more than $100 after a week’s travels.

Enter parking rewards programs, aiming to ease the pain of shelling out dough just so you can leave your car and travel elsewhere. "Frequent parker” awards and discounts are available, at no cost to you. Here’s where to find them.

Nationwide frequent parking programs

These parking companies provide services at or near the nation’s largest airports. With these companies you can earn loyalty awards at rates that are generally lower than airport-managed parking.

Through Park ‘N Fly’s frequent parker program, members earn one free parking day for every seven paid days. Go away for a week and you’ve earned a free day of parking. The free day is available immediately.
