A frightening prospect.
Xulu is right.
The most worrying (sic.) jet flying I ever came across was alongside Libyan line captains, freshly trained on the A320. Their over-confidence and inflated egos led us towards some very uncomfortable situations. (To be fair, the Cubans were no better,)
Our rules did not permit full local crews to operate as pairs. Only one in either the left or the right seat.
So, I too would not choose to travel in the future with any ME carrier which is densely-populated by local crews.
