Who is willing to pay more for such features? Remember now most pilots fly free unlike just about every other online gaming platform where some fee is involved even at the entry level just to participate.
Google Maps has extortion prices as it is. Anytime you start adding 3rd party features, there is a fee involved I'm sure...... Open source programs might be a possiblity for the maps/tracker section if they could be integrated into the old code that runs FSAirlines. Remember too that Joe has done a fantastic job of keeping this site running, much like a mechanic who through the labor of love keeps his restored classic car in "show condition".
Regarding seeing each other and chatting, it is fairly easy to set up a Discord Chat Channel for your airline and invite others.
Regarding see other pilots, simply click their name and then go to Statistcs or Finances and you can see their entire FSAirlines career.
The Statistics section under the pilot name has a wide variety of items if you use the dropdown menu. The trick to finding a specific pilot is knowing what airline they fly for. Perhaps a directory of all pilots would be possible, listed alphabetically?
With other airlines, you can see everything about any airline just by selecting that airline in the dropdown menu and then using the tabs in that section.
If you use the Virtual Airlines tab on the home page of FSAirlines (before you enter the crew center) you can filter that list by country and when you click on any airline listed, if they have a website, it will show in that section.
Time for another video? I can show everyone how to look around our virtual world and see what others are doing. LOL It would be an easy and quick video to make.
WARNING: If you do look around like I have done in the past, you may find other virtual airlines with professional grade websites and operating procedures that will make you wonder why you bother .....
It can be quite humbling but also educational. Much like viewing someone's highly expensive sim rig, we know we could never have one like that but it's nice to look and maybe learn a few things we can apply to our own little operation.
