Both are different field. BBA in aviation is more a management subject it has hardly to do anything technicality it may help you to understand business of aviation sector, how different department works and many subjects will be common like other business management subject. However B.Sc aviation is more technical subject and may be offered alongwith CPL I.e. commercial pilot license or AME I.e. Aircraft Maintenance Engineer course. Don't look at salary. Check what is your strength. Salary ia paid either when there is demand for skill and nature of work. An IT engineer may get more salary than a mechanical engineer but a mechanical engineer may have less hectic schedule better personal and professional life balance whereas an IT engineer may have to work 12 to 15 hours per day. There are lot of permutations and combinations.
