According to this Flyertalk thread, the Avis marketing department has decided to extend the 3,000 US Airways miles promotion. The promotion had expired at the end of March but appears to be back on. The promotion appears to have been extended through February of 2013.
This promotion has been my go to car rental promotion for the last few years. Glad to see it has been extended.
