Im working on one (not to undercut your work Harpsi)- actually if you really want an updated one I cam upload it some where at request because the other things i wanted to do are negligible.
Here are some things I changed...
-all/most Terminal 4 airlines now park at the gates first, then the stands if needed
-Delta airlines also now has a few spill-over stands at terminal 4
-runways 22 and 13 operate together (instead of 31 and 22 which causes traffic jams), and vice versa
-terminal 6 has been shut down, so JetBlue only leaves from terminals 4(for international fights)and 6(main)
- Most terminal 4 airlines are coded to park at their preferred concourse in real life, and in some cases their preferred gate
So as you can see the bulk of the work was done for Terminal 4
