don t waste your time. Dispatcher jobs( and i mean Flightplanner, not Ramp staff ) are quite rare. A lot of airlines only accept their own staff.
For example one of the 3 major carriers in Europe: You can only get a dispatcher by joining their dispatch course sucessfully. If you did the course somewhere else you have absolutely no chance to join. By the way: the course is not 6000$.... its approx 23.000 US$
Sorry, but things are looking pretty bad....
