Forgive me if I missed this somewhere else in the thread, but is it no longer possible to earn the status based upon number of days rented? I've always been Avis First based on renting a total of at least 35 days a year.
I don't do a lot of domestic trips that require a car (almost always less than 12 per year), but when I do, it's typically for a period of 7-12 days at a time.
If I can't get anything higher than preferred plus based on days rented, I really see no reason to continue sticking with Avis. As I'm Plat with UA, I might as well go over to Hertz and get the perks associated with that partnership.
