quick question...I'm still new in the aviation community. Student pilot working on commercial cert. If I were to go the whole cfi route to regionals and if I wanted to fly for emirates or someone like them as a F/O, would it be better to just build experience through regionals with a high seniority and stick with them, or move on up to a major and start off as a noobie? Hopefully the more experienced here can understand my question.
