I hear a version of this question often so I think I'll give an answer. Usually the first question is: what major should I be to get pilot? Answer: Any. Other career fields: check for a degree requirement (usually scientists and acquisitions/contracting). If none, then ANY. Next question: Ok, so the major doesn't matter. What is the easiest major so I can get pilot!? Answer: The one you will love. Management is easier than aero, astro, chemistry, mechanical engineering....etc. But if you love your major, you are far more likely to A) enjoy your experience, and B) work hard and get help. You will probably be happier which will improve other aspects of your performance (MPA, PEA). You will be interested and vested which makes getting help more natural. If you end up leaving the USAF early, you will have a major which will probably give you the most favorable career area based on your interests. One of my good friends was a physics major. He LOVED it but was near the bottom of the major in terms of grades. He enjoyed USAFA, enjoyed his major, and is now at UPT at Vance. My room mate had a low GPA, but had a great MPA. He was a comp sci major and really enjoyed it and was always engaged (even getting through discrete math!). He is also at Vance for UPT! So, what major should you choose? The one you will love.
