There is a freeware application, AI Flight Planner, by Don Grovestine that converts FS9 traffic.bgl files to FSX format. All my WOAI and MAIW flights have been converted and any new ones that come along, I install them to a temp folder and manually put them in the appropriate places. I convert the bgl file to FSX format and you can set the path so it puts it in the Scenery/World/Scenery folder for you. This is
a fine application, and the price is right.
