If I am in the Presidents Club and they call my name for an upgrade and there are many on the list, will they just skip over me if I am not there? Let's say I like to stay at the club until late in the boarding process because I don't like to sit on the plane very long before liftoff. Will they skip over me because I was not at the gate to pick up the upgrade or will they just have to wait until I go to board to alert me of the upgrade? What happens here?
