Colgan, where I just resigned has many pilots under 21. I just turned 20 when I got hired. I actually was put into and upgrade class when I was 21 but told them I was not old enough for the ATP. Colgan is very respectful and does not see age as the problem. As a matter of fact, I am sure any of these 20 some year old saab/beech pilots are more of a pilot than any of these button pusher guys!!!
