More than two bridges, two whole separate lines at the podium. At most places of you miss the early call you are mixed in the crowd. Not at NRT, you can walk up anytime and bypass everyone in line waiting to give their ticket. This was for UA891. I think they did the same thing going the other way at LAX for UA890.
