Rent with Avis, Get Up to 5,000 AA miles until 08/31/14

One of the better bonuses I've seen as of late, and it's not even published on AA's website yet: Through August 31, you can earn 1,500-3,000 bonus miles on American Airlines for renting at an AVIS airport location, by using "MUAA004" as the coupon code on your rental. The earning levels are below:

• Earn 1,500 AAdvantage bonus miles on rentals of 1-2 days.
• Earn 3,000 AAdvantage bonus miles on rentals of 3-4 days.
• Earn 5,000 AAdvantage bonus miles on rentals of 5 or more days.

3,000 miles for a 3-day rental is a great payout (and I'm bummed that I just rented this weekend for a mere 1,500 bonus miles), especially when you can take advantage of great weekend rates, where you generally pick up as early as Thursday and return as late as Monday (with a Saturday involved).

For the maximum per dollar ROI, you can get a one-day weekend rental at under $20 after taxes/fees, netting you 1,500 bonus miles at the cost of $0.013/mile (many miles collectors aim for anything under two cents/mile).

So why can't you just do a series of one-day contracts (i.e., returning a car and renting another one at the same time) and earn more miles? While it doesn't state so explicitly in the terms and conditions, from personal experience, AVIS has had a history of considering those types of rentals to be a single rental for the purposes of promos. But your mileage may vary, and if you this route, you'll likely have to contact them a few times to get results. And of course, you have the inconvenience of returning to the airport and going through the process each time.

While the terms for this "Make a Statement" promo suggest that you use a certain AWD number assigned to AA, you can combine most coupon codes with most AWD numbers, if you had a favorite one to use. If you don't have an AWD and found this info helpful, please feel free to click here or use AWD U4517031 (which also nets you up to a 35% discount).

Full details of the promo can be found here. And if you don't have an AAdvantage number already, make sure you sign up for one!
