Hey Cliff!
Hope all is well with you in NBO.... as far as Global Services goes in SA I applied with them a few weeks ago... they advertised that they were looking for MD80/DC9 CA's and FO's... I applied as an FO because they did not require a type as part of the requirements... a week after applying I was emailed and informed that they only want people with time in type.
I know nothing beyond that.... although I did find the pay to be a little low for the areas they fly into.
Good luck and Cheers!
