After reading all the above I feel I might have completed the wrong course. Dec 2000 I completed a MSc in Aviation Management from Southampton University, it was a good course which combined aviation modules whith those from the MBA. In career progression terms it has not helped at all, and I'm still at the same level as I would have been if I didn't have the MSc. I am now studying for a MA in Management.
Good luck with the course though.
