Via TM Travel World, American is offering 3000 bonus miles for a 3-day Avis rental by using coupon code MUAA022 through December 31.
The page trumpets a discount as well but you do not need to use their discount code in order to get the miles. And the offer also provides 1000 miles on a one or two day rental.
This matches the US Airways offer of 3000 miles for a 3-day rental valid through March 31.
Of course some will prefer to just rent from National, as they’re still making their Executive status level available to anyone who signs up… UPDATE: has been pulled apparently....
