Been very lucky as a silver so far this year. Overall, I'm at 818.818% for mainline Continental and Northwest flights (I have a ton of ERJ segments to small towns).

For Continental, I'm at 5 upgrades out of 7 eligible flights; 3 were on Y fares and the other 2 were U fares. The segments not upgraded were O fares. My average for Continental is 71.429%.

On Northwest I'm 4 out of 4 flights, for an average of 100%. 2 flights were V fares, and the other 2 were Q.
