I know this is all in hindsight, but I now regret getting Hertz points on my rentals. Should have gotten one of their partners back in the day (e.g., United/Marriott??), even if the earning was small. Better than having points expire...
Sadly I looked and outside of just using the points, they don't have any transfer partners (anymore)

I wonder if my email doesn't stipulate # of points set to expire, it means mine will last longer? I was effected by the 18-to-12-month expiration change where I had to get them to re-instate my points. I wonder if that process 'reset' my points date?? Hmm..
