La Spina noted that up until the arrival of the 787-9 in the Qantas fleet in 2017 the airline had first and second officers that were unable to achieve promotion because the captains above them were not retiring and not leaving the company.
No, the airline had first and second officers that were unable to achieve promotion because the airline had been shrunk, routes were dropped, and resources were sent elsewhere. Pilots have always had their careers, then retired and been replaced by other pilots. To suggest that there was some sort of new phenomenon of captains not retiring is bull**** of the highest order.
