Will having four years of experience in the marines being in the infantry help me get land a airline job easier after I get all my certification at ATP ?
Sorry but no. While we all respect your service, Airlines hire experienced, well trained pilots. If you’re talking about the Majors, you’ll also need a 4yr college degree.
It will look good on a resume, but at the end of the day, the airlines are looking to hire pilots with flight time. The regionals are not as selective as the majors, flight time is king there. At the majors, the airlines will be looking for thousands of hours of flight time, coupled with a college degree and work experience. The military time will help in regards to the work experience.
