You don't have to kill your time on that coz the job on air port is not best as all coz it just like servant job . which means after you finished your course to a pilot then you didn't come a pilot in once you start working inside country . generally its kill your time and age so try another bussiness like marketing or bussiness administration coz am telling you I'm on working on it . so son be careful on your choice coz your decision is made you life better or bad and that is concern on you desicion ! Thank you !
