Degrees are available in the field of aviation sciences from associates to masters level allows individual to join this profession at any level to initiate studies to get entry in the field or to upgrade the level by earning suitable degree. Your best bets are to get a degree in either engineering or another form of aeronautical science. These degrees will help you to prepare for a career in aviation.
There are also very specific courses and degrees for aviation. Look at schools like Embry-Riddle or the Univerisity of North Dakata. Both of these schools offer a degree in professional piloting. Yes by a different name but that is what the degree is. These programs include flying as a part of the degree.
Another course to think about is getting a degree outside of aviation and learning to fly on your own. This is not a bad idea in case you change your mind about flying or find yourself unable to fly. For this I would suggest a business degree, this is always a great degree to have and will allow you to go places whenever you want. Including into airline management. While getting this degree you can go out to the local airport and learn to fly at a professional flight school.
Airlines are not very concerned about what your degree is in. They want to see that you completed the degree, this shows a level of ability and commitment they want to see. There has always been a joke about getting a degree in “Underwater Basket Weaving” and this being good enough for the airlines. From my past I would completely agree.
The bottom line is get a degree in something that interests you that will allow you to finish a four year degree program quickly. Learn to fly on the side and you will be set to become a professional pilot.
