I agree with Nobleoz...recently UA has become really stingy on doing upgrades even when there are lots of seats available. I'm on the waitlist of a BKK-NRT flight later this week. There looks to be about 40+ BC seats available. On the flight from NRT-BKK, they didn't upgrade me until the day before the flight when there were over 50% of the BC seats open. Being a 1K for the past 5 or so years, I'm getting frustrated about not getting upgraded more in advance. That's one of the main reasons I stay loyal to United. I appreciate the upgrades that UA give me, but I still feel UA needs to take better care of the customers who give them a lot of business. Just my opinion.
