Don't know for how long, but realized that all my weekly flights are inoperative. 24Hr flights are fine, and FlightPlans.txt looks good.Have tried:1) Going back to original traffic.bgl file and recompiling from FlightPlans.txt.2) Installing TTools 1.3.1, which I hadn't gotten around to doing. Again started with original traffic.bgl, started FS2K2 to get it to process it.3) Running TTools in Win2K compatibility mode. Running on WinXP.Any help greatly appreciated. This could be big, big trouble.Dave

Discovered what is happening.Flights at 24Hr take priority for gates over WEEK flights, even though the WEEK flight leaves first and is listed first.

Up to now we believed that the flights appearing first (at the top) in our Flightplans.txt file take precedence over the flights further down the list.Are you saying that a 24hr flight takes precedence over a WEEK flight, regardless of its position inside the Flightplans.txt file?Stamatis
