A good point you have made at the end of your post thier about the MPL scheme being only accepted. No one has yet touched on this yet but the moment I saw the thread the exact same question popped in to my head.
The answer?? Well who knows?? It could be it could be not. Its a way I think of connecting the students more with the airline and possibly an aid to keeping them in for longer. It is a slight worry but hey ho.
Best of luck
