Airbus (for example) time and look at the future. What do you think they'll want to do and why? They'll choose more relevant experience and greater future earnings. End of.

When the scheme falls flat on it's face due to lack of applicants you will be vindicated. But as you have harped on about this for years (sounding like '5 stripes' in the process) I doubt you will be. The scheme will run as applicants who meet the requirements will be selected. If you really want to be a barrier, go to the flyer show and confront the flybe team head on. You will have the perfect forum for change.
