The 3000 US AIrways mile bonus for 3-day Avis rentals that’s targeted to US Airways elite members doesn’t seem to be restricted to elite members.
For a rental a week and a half back, I had the following activity post to my US Airways account today:
AVIS 2010 PREF. MEMBER 3000 MILE BONUS
I am not a US Airways elite member.
Oh, and in addition to the 3000 bonus miles I received 150 miles (50 per day x 3 days).
