I have been Select for a number of years also. I've been told that 6 rentals of at least 2 days each in 6 months makes a Preferred eligible for Select. Selects get an automatic complimentary one class upgrade if available...and "available" only means if the location has an EXCESS in its judgement. Have never heard of any entitlement to two class upgrade. I'm not sure there's much benefit to Select. LOTS of folks get one class upgrades. I like that suggestion on reserving compacts....I'll try it!
