postgrad courses in aviation management
Suggest you might also have a look at the UNSW Aviation postgrad courses which are also available on line. They are offered by distance and fees are eligible for the Fee Help loan system. Without a bachelors degree you can still enter the Grad Cert, and work though the Grad Dip to a Masters Degree.
A close look at the different course outlines for the courses offered by the different institutions would inform you as to the strengths of and differences between programs.
These programs won't guarantee you a desk job, but if the courses are good quality then you should enhance your chances of interview and then of employment.
good luck
