AA and licences
It depends what position you apply for...
FO's: hiring only locals, whatever for AA Malaysia, Thailand, Indonesia or Philippines. CPL is a min.
DEC: locals or Foreign with ATPL but ONLY possible with AA Malaysia. A Malaysian law imposes hiring ONLY Captain level in Malayia.
With a UK CAA CPL, you can only apply for FO AND you must be a local from one of the countries listed above if you want to join AA.
Hope I am clear.
