Yeah pretty much, I don't know what program your using to track them but this is what I found (it's about 'FlightAware' but they're probably all similar?)

There are limitations in the flight-tracking data. FlightAware and Flightradar24 have gaps in radar coverage areas. That forces their computers to make assumptions about flight paths that can make a flight appear to pass over an area—North Korea, for example—when it actually skirted around it. United Flight 976 from Washington's Dulles International Airport to Dubai looks like it passes over northern Syria on FlightAware, but each day it actually skirts the Syrian border to the north and travels down the Iraq-Iran border to the Persian Gulf. Flightradar24 shows the path avoiding Syria
