The biggest downfall of PIA is and always was corruption. Constant bailouts by successive governments were deliberately plundered and given away to friends and families of so called chief executives who have and had no interest in helping the airline. Everything you have mentioned in your post is very accurate, however these are sadly all symptoms of the main cause, and that is decades of corruption and embezzlement. Even recently a tender was put out to upgrade some 777 interiors and to develop an indigenous IFE system. That money was awarded to a so called company with absolute no experience in this sector. Guess what, the money disappeared.
