Rats. So apparently they're getting rid of the "rental days" option for earning the status. It was typically through "rental days" (because I do a handful of week or two-week rentals some years, but not enough separately rentals) that I'd qualify for Avis First in some years.

Though not that (as someone who always earns partner miles/points and bonuses on same, on every single rental) I get that much out of Avis First. Avis First doesn't seem to upgrade me (from lower-class cars) much more than Avis Preferred (which still upgrades me quite often) does.
