Guaranteed doesn't quite mean what I suspect you think it does, the so called guaranteed way to licence heaven works (loosely, sort of) as follows.. .. .Throughout flight training numerous phase checks are conducted to monitor the student's progress, each phase must be up to snuff prior to handing over additional greenbacks for advancement onto the next phase. Should a student display the innate flying talent of a rabid monkey then all bets are off, the guarantee disappears and the final cost for achieving CPL/IR standard goes through the roof and busts the $23k budget wide open.. .. .Mr or Mrs average with a lot of commitment can,as advertised, get to professional licencing levels on $23K (recommended however that you do read the fine print) but no school is going to supply flight time at a fixed cap to the truly hopeless. . .. .As for where you can use the ticket once you have it; the laws of aerodynamics are the same everywhere but so are the dictates of politics which put obstacles in the way of employmnent and licence conversion.Buyer beware.
