Folks, Heads up for those of you who are not used to the Continental upgrade scheme: If you're high up on the upgrade list and it looks like you might win the battle, don't leave the gate. They will call your name if you get the upgrade once. If you're not there, they will give away the upgrade to the next person on the list. Great cost serving measure. My flight to SFO is delayed 30 minutes + today and the GAs didn't know when they were doing the upgrades, which means an hour at the gate instead of at the club for free beers.
