When I was 62 , I and another 62 year old asked to do job share ie month on / month off at an airline just to the south of UAE . Despite the obvious benefits to said airline , ie 1200 hours Captain time for one shared salary , the muppet we were talking to did not understand the concept , thought us evil expats were up to no good , and refused . Two months later my colleague died after a stroke at the controls and I resigned . Two very experienced captains lost . Any airline that can introduce one on / one off for older crew are being very far seeing . The constant Night Returns to the sub continent were the most exhausting flying I ever did .
