>>>From what I've heard, LH are chiefly interested in people with a business based educational background (unless you want to become tech/cabin crew).
No, for LH it´s not so important WHAT you study, it´s important HOW you study it. I did an internship at LH when I still was at school, and one at in an airport´s legal department (I studied law too).
One piece of advice (if I may): I´ve found LH to be not very responsive to eMails, in many respects. So why not just send a letter to Human Resources? And I mean a real world letter on real world paper delivered by a real world mail man
. They´ll certainly send you information about internships.
BTW, you should be in the second half of your studies, what´s that in Australia, 3rd/4th year?
