Perhaps if certain airlines and countries reviewed their restrictions on Commanders aged 55+, things might be slightly less heated?
I can understand the frustration of a newcomer who sees traditional FO seats being taken by ex-commanders; however, why did the airline require them to give up their commander status in the first place? If there was (and I'm NOT suggesting there should be) a mandatory retirement age of 60 from flying commercial air transport aircraft, then commanders could stay in command and newcomers could more readily fill the FO seats. No doubt the unions would have a strong view and there would, ipso facto, be a longer wait for command in the first place?
