Probably best way to go about it is ask for holiday "work experience" instead of just a job.
You sound like one of my sons----he would have done anything to be near planes.Got his PPL ,saved up for CPL ,then blew his money on a car.
Dont know if this caused him to change ideas or the fact he found out he needed laser surgery on his eyes for 100% vision and that may hold him back from the airlines.
Then went to an aviation engineering school for a year(government sponsored),all the students put in regimes and he got chosen by a major airline,along with many others.
Now in second year apprenticeship and loves it--works on jumbo,s 767,s etc.
He gets the best of both worlds as he pops over to the simulator section after work and does a bit of flying.
so kid ,start looking into things.
But for the present ,try the companies that are at the major airports----right in the middle of the action .
If you get in ,work hard ,show a lot of interest ,ask questions etc--
a good reputation and word of mouth go a long way.
