Advise For Students
I agree with most. If you want a CPL or even an ATP later and work in GA then get you CPL the cheapest and easiest way. May be it's a good idea to get an instructor rating making it easier to get the first job.
Don't fall for the flashy advertisements showing B747 flight decks and fellows in uniform telling you "enrol with us and that seat in the B747 is yours". Don't fall for it, that's bull.... A CPL and a CIR (ME) will NOT put you in line for an airline job. Sorry. 3,000 hours and actually hoilding the ATP won't either. You have already adopted GA habits making unsuitable for making money for an airline using tools such as B747 or Airbus (even stated by QANTAS in aviation magazines several years ago).
If you want to be an airline pilot then get yourself a degree, either a BSc involving electronic engineering as well as transport management. There are aviation degrees offered; however, don't worry about the Australian Universities offering an aviation degree, they get you nowhere any more because they are crap.
For aspiring airline pilots you would be best off by learning to fly and then study aviation to the internationally recognized JAR-FCL competencies. Which Univeresities? Lund (Sweden with a branch in the USA) , Embry-Riddle in the USA, Cranfield University in Oxford (UK) etc. That's where international airlines send their cadets.
