GCAA licence

[Dam]

hello

I used the search tool but did not find anything so here it is:

I have worked as a Ramp dispatcher and flight dispatcher ,unemployed at the moment thanks to the crisis and unstability of the aviation business...

I hold a PPL but it is not valid anymore as I haven't flown recently (last time was in 1997!)

still hope to become a pilot one day

You hear a lot about flying in the US or in Europe

What about flying in the emirates ? Does anybody know if it is much cheaper ?
Would it be easy to convert from a GCAA licence to a European one or FAA one

Thanks
