Cannot speak for reputation overseas but can speak as an expat working for QF in OZ
By and large the QF Pilots and F/E's I worked with were very decent and professional individuals.
Of course there were the odd individuals as I have found in all airlines - there were certainly a number in BA/BOAC.
I was seconded to QF from BA in the mid 1980's as an F/E. Very happy days.
QF Pilots and F/E's have earned a reputation for which they should be proud.
Kind regards
