Swinging The Lead
I'm not sure who you talked to, but I don't think there's much truth in what you were told! However, there was a very brief period when Virgin accepted applicants for long-haul Second Officer (cruise pilot). There was also a period when the airline recruited co-pilots for the Virgin Sun operation, and in both of these periods the airline, when looking at low-hour civilian-trained pilots, stated a preference (not a requirement) for CAP509-ers. That route is no longer valid, but, even then, stating a preference for a particular format of training was not the same as stating a preference for certain schools. The fact that some airlines still refer to CAP509 training is testimony only to the ignorance of their recruiters.
The fact is that airlines care only that you have the qualifications to make you eligible for whatevr they are offering. Where you obtained those qualifications is irrelevant, so long as the training was legal and carried out by a bona-fide school according to current rules and regulations.
If you seriously think that airlines like Virgin greatly care what school (or whether you were mod, integrated, CAP509 or whatever) you went through when their minimum requirements are for 3000 hours with 1500 hours commercial or military jet, you have misjudged the system!
