Hope this is the right section for this post. Tommorrow afternoon I will be (once again) heading across the Atlantic on UA; my third such trip since January 2010. Routing ABQ-ORD-MUC-VRN. I have premier (no prem exec or 1K) on UA, yet have now struck out 3 times in 3 attempts at trying to use 10K MP miles to upgrade the trans-atlantic segment. FWIW, each time the ticket has been a full (Y) fare tkt; yet, I'm never quite high enough on the list. J is always full; last time I came the closet and was #1 on the un-upgraded list. This time--once again--I'm showing as "waitlisted."
Does anybody with an inside track have any advice to give on how to get the upgrade? Anything I can do at this point before I get to the gate tommorrow?
