thesilb is correct. CO policy prohibits standby for upgrades using miles, even if BF is not full. (But you can upgrade less than 72 hours prior to a flight if you buy a "Y" fare and use "Z" class--not for most wallets.)</font>
I thought the poster must have been mistaken on this point, until I saw who it was from. Could this possibly be true? I don't recall seeing this in any OnePass literature or FlyerTalk posting - this is news indeed. Please note that I'm not endorsing the 72-hour rule. I'm just a rube trying to figure out what my options are.
