KP. You missed my point, slightly. Deprogramming then reprogramming is not easy; in some airlines eyes. I've done it myself as captain, many times; no problem just hard work. That's called maturity, realism, singing the song of the piper who pays you. Some airlines think F/O's are not so capable; perhaps from experience. When there is a glut of F/O's they choose the raw recruits: when there is a shortage of captains they have no choice.
