Do any UK or EU airlines expect applicants to have ratings? Only SWA in the US, good enough reason not to apply in my view.
As far as bizjet ratings, it is a crap shoot which rating to get, so what is the point unless guaranteed a job if one got the rating. Then, the question has to be, "If they want to hire me, why shouldn't they pay for the training?"
Next, what good is the rating without any experience in the jet? In the US, anyone with a rating and 2 hours in the plane would be laughed out of the office in most reputable operators.
