Hi Sophia. You can definitely pursue Bachelors in Business Administration ( BBA ) in aviation after the completion of 10+2 . Rather, an aspirant is eligible for BBA ( Bachelors in Business Administration) in Aviation if he has passed 10+2 or equivalent from a recognized school board. 

Dear Sophia, if you have finished 10+2 and have scored a minimum aggregate of 50%, you are eligible for pursuing BBA Aviation course. Most institutions offer the course based on group discussions and personal interview. While few institutions conduct their own entrance examinations.
