The problem isnt the airline, the problem is the guys that came from africa at amu are twisted, evil and stupid.(some exceptions) Then you got the english as a second language south americans who couldnt go anyplace else because of lack of document, english or flying skills. Only Vietnam Airlines is gonna ask questions about amu due to obvious reasons.
On top of the amu bad guys you have the chinese penny pinchers, who ridiculous budget affects salary, training, equipment, quality of staff etc etc. On top of that any lack of growth or expansion of the airline a dead end and a heaven for guys who cant go anywhere else.
