You can check avtech2000 which is base in UK for online studies, as far that i know only them are doing the flt dispatch course online but u need to take an exam when you complete. It's only gives you certs for City & Guild UK approved but not FAA.
If you need FAA approved you need to go to US to do it. I recommend Sheffield in Florida. The best step is to get a job first in baggage/ramp and work towards dispatching like i did 3 yrs ago.
