Hi Little Mo
There are 2 pilots from South Africa who are working at AJX, both do not commute from RSA .
There was a third who was employed around 2004/5 (?) He tried to commute from RSA and it turned out to be very difficult, he did not stay long.
That may have influenced a reluctance to employ people from RSA who will commute from there.
As always, best is to contact the contract company directly, they will have the best gen.
Good luck
