Hi Buzz,
Thanks for writing and I commend you on thinking about an MBA so far in advance -- the foresight should definitely help you frame your application.
In regards to your lack of promotion, you'll want to definitely show a measured increase in responsibility over time. Additionally you can instruct your recommenders to mention in their letter that a lack of promotion isn't a poor reflection of your work but rather standard company procedure.
Best of luck,
Daniel Richards
