Wow - I truly am shocked at the percentages in this thread.

For points of comparison:
On AA this year as an EXP, I'm 100% - all flights - incl 2 south am. *
On UA this year as a 1K, I'm 100% of all requested upgrades (11/11) - incl 4 trans-atlantic. *
On NW this year as Gold, I'm 93% (13/14, only one hasn't cleared - MSP-SNA)
On CO this year as NW Gold, of my 16 flights, 13 have been RJs - blecch- but I'm 3/3 100% on the mainline planes (IAH-MID/Q, PVR-IAH/N & IAH-SAN/B)

The poor CO Plat percentages here are just amazing to me (though I have certainly been very lucky so far). You guys stay with CO again why?

[*- Also note that all of my UA/AA upgrades have cleared at their respective 100 hour marks or prior - none waitlisted after that window opened. All three of my CO upgrades cleared at checkin or at the gate, including the two Mexico flights that weren't even half full in First upon departure - is EUA just a myth @ CO?]
