Suggestions:
1) If you get a job as a dispatcher, remember that you will quickly get to be known by your regulars. Make sure that you don't piss on your chips so to speak by doing dodgy turnrounds or molesting the cabin crew (like one chap I know - after ten years or so, he's still the 4rsehole he ever was).
2) Have some calling cards made up so that you can tell people who you are.
3) get a reputation for being useful to the crews you handle and they will speak up for you in interviews.
4) It does work - I know of quite a few former dispatchers who have "moved on".
5) Be prepared to make baked beans on toast your favourite meal because left over pax and crew meals will be your staple diet (cos you won't be able to afford "out else").
