Hi Alex
I am not aware of the scnenario in Europe or for that matter Austria, but having come into the Aviation field from a background
identical to yours I have some suggestions.
1, You have to get some industry relvant qualifications.Without this with your current background it is difficult to get in!
(I did my bachelors in Chemical Engineering and however hard I tried to convince potential employers in the commercial side of aviation, I got turned down everytime).
There are a number of good courses which have universal acceptance many of which can be done by self study. The courses offered by IATA are an example(In my case I took their travel agents training programmes but there shouyld also be airline management related programmes available).
2, Once you have these it is easier to get in at the entry level at a small to medium level organisation(ie if you get turned down by the big ones).I am sure these vacancies do
exist in Australia.
3, With some industry qualifications and more importantly having acquired experience after one or two years, the access to the big players will definitely be easier.
Hope this will be of some help
