From upgradesuccess.com:
Entered Upgraded Percent
DL Delta Platinum 35 32 94.3%
DL Delta Gold 69 53 78.3%
DL Delta Silver 76 55 75.0%
NW Northwest Plat 370 340 92.2%
NW Northwest Gold 225 163 74.2%
NW Northwest Silver 241 166 70.1%
Now of course these stats have severe limits, esp with Delta's having so few flights entered.
