my experience
Swannie, I spent three years at uni, came out with degree in Aviation, and then another two years to complete a degree in Business.
I know all of the nay sayers on pprune would say that the degree is not worth the paper it is written on, however in this day and age you need to have backup plans and have to be as competitive as possible when applying for a job.
Has it helped me so far? Maybe not. Will it help me in the future? Maybe not. But if two pilots with exactly the same flying hours and qualifications turn up to an interview, which one do they choose? The guy with the degree or the guy who did straight flying? Maybe the person conducting the interview might see that you are willing to go further than the bare minimum, willing to learn as much as you can in order to get the job.
All comes down to life experience.
Good luck. If you do choose to do some form of business course I can guarantee that you will enjoy it!
