Since night work/fatigue is an issue and maybe a reason for people to move on as soon as they can(?): would ops like DHL or night freight in general be a little more generous with older applicants if they already bring shift work experience?
Thinking that if you can do the night hours/fatigue management and don’t have as many other options to fly jets or make it big elsewhere (due to age), you are more likely to stick around. Would they consider that a plus enough to balance the disadvantage of being a late starter?
