My SO and I are flying EWR-LIS tonight (CO 64). When I look at the PDA site, it is showing that Economy is full and BF has three seats open. The flight standby list has three names on it. I know that BF requires miles + co-pay for an upgrade, but is there a way to ask in the PC about the possibility of an op-up if they need the seats? Will only the GA do this at the gate if the seats are needed (I know it's not happening if they aren't)? I lucked out last year flying EWR-DUB and we were both moved to BF because the flight was oversold. Anyone else have any advice?
