Right say for example your flying from IF to Sw but you pressed on duskwood by mistake... now your flying along like **** WTF i never meant to do that well there is a way to still stop at SW and not waste so much time... yeah sure you've spent more money but this will save you money in the long run...
Right what you do is at any point in the flight between the point of take off from IF to the point where you pass by SW and it takes the money... all you have to do in mid flight is log off and then back on and woot... you land at SW
Not really an exploit just a little trick... and i have no idea if this has been posted before
