It would be easier if airlines hire there own people.
Easier for who? And it's 'THEIR own people'. I think before you try to find a job in any sphere you should improve your presentation, try to learn a little about how business works, and above all concentrate on what you can offer a potential employer rather than on the perks they may offer you.
I appreciate that you might be very young but it is never too early or too late to learn good habits.
