On my flight today, I noticed that I had the option to connect the pushback truck prior to door close. As a former ramp agent, this is an option I've wanted for a long time. At my airline, we always connected the towbar and pushback truck ASAP. Most of the time, when a turning aircraft arrived, we'd set the chocks and insert the bypass pin right away, then we'd get the truck connected to ensure a more rapid departure.
Thanks again for adding this feature to GSX.
Best,
