looks like you and me have got a bit in common scrummer-trying to get on a dispatch course,looking to go to dubai etc.
with regards to the former,the only way to do FAA is abroad-believe me when i say i've researched my proverbial bollocks off on this subject!US seems to be the best place although it'll cost about £4,000 to do it all-in including 6 wk course/accomodation/spending money etc.if you can't afford that(which i certainly can't at the moment...but i'm working on it!),then the city and guilds seems the only other route-i'm sure you know all about this anyway!
if the FAA interests you there's some good sites out there to look out for dispatch schools in the US.try
www.airlinedispather.com-this is the school i intend to go to once i've figured out how to rob my local Lloyds bank!
if you know of any other info not mentioned here,let me know...i'd be very interested to hear.
good luck mate....who knows,maybe we'll be dispatching together in dubai before long!!
