It still didn't work because prized son was never going to make it as an airline pilot.
Thread creep I know, but you are a little too quick to point the finger. For his limited flying hours, the individual concerned actually flew the 737 simulator and real aircraft quite well. Certainly a lot better than more experienced GA pilots who are now in the airlines -and believe me there are some real bogan types who scraped in and are a pain in the neck on the flight deck.
. On more than one occasion this young chap was rubbished at the interview by chief pilots who were obviously surprised at seeing a 737 endorsement on his licence. One arrogant bad mannered oaf (unable to get into an airline himself) told him to piss off because he had a 737 on his licence and it was automatically assumed he he would apply for the airlines once he picked up sufficient hours. That was probably true but hundreds of GA pilots have done the same thing for 50 years.
