Wow, this is some really great insight. I knew more went on w/ RON aircraft, but never had an idea unitl know about what really went on there.
As a note, I notice some airports pull jetways back, but others leave them in place. Some airports do both. IE
: at GPT NW
pulls back the jetway from its RON plane, but CO
leaves there in place at the door. ASA pulls theres back,but its due to the need to close the regional jet door, and that can't be done w/ the jetway at the doors threshold.
I wonder if the retracting jetway is a airline to airline thing.
