Recently(June 1st 2016) I traveled on EK433 from Brisbane to Dubai. I often checked the flights progress on the entertainment system, which is pretty accurate for the purpose. Anyway, when I returned to Australia, I checked the FA site to check the flight path to recreate in my flight sim. I noticed though the flight path displayed in FA is very different to the one I flew. When I looked on flight radar 24 history, theirs is pretty spot on for June 1st.
I wondered how you determine the flight path for each flight?
