Hello,
To make boardings a little bit less scripted and predictable, and more lifelike, could you implement a less linear method of boarding where the flow of passengers is less uniform, more random, with an occasional late group or individual? At the moment, there seems to be a fixed, constant flow of passengers. It would be nice if you could add some disruption to this. "Final boarding call for flight XY" comes to my mind, where one or a few passengers are still to show up. Maybe GSX could even send a pop-up message asking if the captain is happy to wait or decides to depart (within certain rules and tolerances). Something to make boardings always a little different, unique.
