(I hope this is the right forum for this, I'm a bit new, though I've lurked a bit.)

I'm kind of "starting out", and while I'm reasonably well traveled (though probably not by FT standards), I wanted to know if there was some advice about frequent flyer programs. In particular, I wanted to know if some programs had policies that were better than others. And somewhat related to that, are there any lifetime programs that are worth pursuing (my understanding is that AA has one at 1M miles, but that sounds rather daunting to me...).

Thanks.
