MVP Gold, here (not 75K). Unofficially I think I'm running 20-30% upgrades for the year on DL flights. I get much better success on mainline, but I've even had Connection flights where I caught the upgrade (DTW-AUS). Got it again tonight, 2 of 3 so far this week (tonight was a 757 AUS-ATL that was nowhere near full). What are other's success with DL upgrades based on AS status?
