If its going to make you take longer to finish school...its not worth it. An Aviation degree is still good enough to get an entry-level job in a variety of industries...turning that into a successful non-aviation career has everything to do with your personality and nothing to do with what your degree is. Remember, a bachelor's degree is there to get you your FIRST real job...that's it. All future jobs will weigh your work experience more heavily than your degree.
If you want to do business, you can get an MBA even if you didn't major in Business as an undergrad.
