Whether you will learn about linguistics depends on the curriculum of the course. Linguistic studies are incorporated in some programs, often where the course includes language, communication, or humanities. Courses in law, such as BSc LLB, may touch on legal language and semantics, while hospitality management (BSc HM) might include a discussion on communication skills and cross-cultural interactions. In business-related degrees like BBA FIA, linguistic aspects may appear in business communication or international relations subjects. However, aeronautical engineering and airport management generally do not emphasize linguistics.
If linguistics is not in the core, you may be able to look into it outside of your curriculum through electives or interdisciplinary projects. Many institutions offer students elective courses in linguistics, particularly if your subject involves international contacts. If linguistics is really of interest, you should be able to locate options in the course syllabus or by seeking an academic adviser.
