Just a quick one, I've already modified the relevant traffic bgls in my WOAI packages to get the traffic at VHHX. Now I have an airport full of traffic and its great. However if I download and update for a package, lets say Dragon Air will it overwrite the modification I have already made and will I have to go and do it all over?Any help thanked in advanceGeorge

You will have to modify the flight plan for that updated airline.Which is why I have only the cargo, GA and military flying into Kai Tak, and the passengers into VHHH.Fewer changes/ updates.
