I made CO Infinite Elite just before they cancelled that program. Those of you that remember Continental Lite will realize how well deserved that was..... But I don't fly CO routes much now and have been Chairmans Preferred on US for a couple of years. My best experience was by earning AA Platinum through flying the US Airways Shuttle - I never got on an AA plane. They held my status last year but have now downgraded me to Gold - I still have 14 Upgrades.... Anyway, my question is: How do I find out which programs offer Lifetime Membershp? I've also been Platinum with Hilton for a few years - do they have this benefit?
