I was unable at this time to update the Horde icons in Northrend; my char can't fly there yet. The rest of them are as accurate as I could place them. I checked every FlightMaster location in the game.
Let me know if you encounter any mistakes.
I added a few comments within it, but you'll need to use the "
Notepad++" editor to view them (and the lua code itself, properly).

Also, if you're going to use this, rename the file by removing the word and the hyphen ("UPDATED -") from the beginning of the filename.
