Has 65 not always been the international standard for retirement as a Captain? Certainly is in Australia, Singapore, Hong Kong & Japan (maybe 60?). Not only effects PX just ask PNGAir, Hevilift, TropicAir. Dam you PX management for following the rules!
CAR PNG has no limit on age domestically. Contract requirements and company requirements vary. Lots of pilots over 65 operating in ALL companies in PNG and that’s nothing new.
