Heh. I actually literally *just* got the e-mail from Amtrak about changes in their guest rewards program - the shift towards revenue based miles and all that. Their miles still expire, though now they count activity as "earning and redeeming miles" but that's really particularly helpful in my opinion.

I agree that any kind of chart/post like this would need to be detailed about the kind of activity that prevents or doesn't prevent expiration; that's why I'm hoping others post and contribute, as I tend to stick very loyally to a few select programs and know their rules, but am unfamiliar with the rules of those programs with which I stay once every couple of years.

Thanks for your contribution - I'm editing the above post to add what you said.
