FSAirlines

i started an airline (i have had to delete) and bought one 727-200
i then downloaded the client and signed in
then created a route from manchester- gatwick
booked the flight and loaded the game
i then set everything up on the client
then it reset my game shut off my engine and said i have compleated my flight.
but i had no passangers/ cargo board so no money
and also i made a huge loss
and had 80% flight review because i landed at the wrong destination (i hadent even taken off and i was at manchesyer)
and i didnt turn my landing lights on
whats happeing to it because i have no idea
i use fsx

Did you have parking brakes applied when you started?

sometimes i did

I've heard of problems with that. I think the way to solve it is to just keep parking brakes OFF for the duration of the flight until you want to end the flight.

Is this with the FlyNET client or the FSAirlines client?

either one, dont start the client until you are sitting on the tarmac in the game. if you start the client while still in the main menu or when FS is loading up it will reload the game and screw things up like what happened to you.
