As a CO Gold, heading for Platinum, I've received absolutely nothing out of the ordinary.

There was a recent thread in the CO section about how CO was sending out "Thank You" kits (containing PC passes, upgrade coupons, etc.) to a narrow subset of OnePass members... there may have been a strategy to the list of recipients, or not... all I know is, I've spent $20,000+ with this airline this year; I think I should be in any group of customers getting a handful of PC passes as a thank-you; thanks to FlyerTalk I know they were being doled out, but not to me; and I'm unhappy. That's the crux of the problem, right there.
