I purchased 2 tickets in Economy (V) for EWR-LAX on 9/2 and returning 9/7 (mid-week flights over the labor day weekend). We have been waitlisted for the BF upgrade using miles and the co-pay. Does anyone know when the waitlist will clear? I understand that they want to try and sell the seats, but at what point do they call it day? Also, if we waitlist up to the day of department, do I have to do anything different or make any changes if it hits the 24-hour window and we can check in?

Thanks!
