Here's the completed GSX Profile for '(KLGA) La Guardia Int'l' - by FeelThere

The airport primarily accommodates airline service to domestic (and limited international) destinations. As of 2019, it was the third-busiest airport in the New York metropolitan area behind JFK and Newark airports, and the twenty-first busiest in the United States by passenger volume

Google Maps - 40.7775031667529, -73.8739656607106

- Custom vehicle positions, marshaller positions, cargo vehicles and cargo loaders. 
- Custom pushbacks with many having multiple waypoints so the aircraft can better follow the pushback taxi line.
- Mostly jetways

Installation: 
Extract the zip file and move the .ini file to %APPDATA%\Virtuali\GSX\MSFS

Get into the habit:
When the airport loads, it's recommended to reposition the aircraft at the same location. The aircraft won't always load at the GSX position so going to GSX menu, hitting "Reposition Aircraft" and then selecting "Reposition here at current gate" will put the aircraft in the right position where GSX was told to put it. hopefully it gets fixed one day.

Since my oven has more intelligence than me, there may and errors or small changes needed. Just let me know.
