Keep checking the flights for R/RN and when it changes from 0 to 1,2,... It should clear your upgrade automatically but if it doesn't contact UA and they will manually clear it.
How do I check for R/RN? I've been trying to find it on the United site for the past week and it doesn't seem like they offer that option anymore to view next to Fare Class. Where should I be looking?
