I'm not sure what drives your future but FWIW....................
I have a few close friends who have MBA's. Every one of them is wealthy!
Some have turned down salaries that would make VERY senior Fedex Captains drool.
I have many friends who, like myself, are Major airline pilots. None of us are wealthy!
I am working on my MBA at present and have already had job offers prior to graduation. There are many opportunities for MBA's out there. And I mean serious opportunities!
My glass is half full with respect to moving to another major sometime in the future. However, it could be years and the options are few. Unfortunately, as small as this industry is, they always will be.
An MBA may be useful with your goal of getting to one of the few worthwhile majors. It will be a very powerful tool should you decide on a better career.
