I hold a degree in aero engineering. During the education there were several paths you could go which affected your choice of courses to take. Construction, maintenance, logistics... I'm thinking most AE
programs will give you the option to tailor the education towards maintenance, if that is what you desire.
I know that in some fields, in some countries, a degree will not help you get a job at a lower level. They're not too interested in hiring someone with an engineering degree on the floor, as they (probably correctly) assume that as soon as there is an engineering opening that individual is out the door again. "Sorry, overqualified, back to the unemployment line you go... we'll hire some git who's got a degree in burger flipping instead".
I thought I was doing good trying to avoid those airport hotels... and look at me now.
