OK, I'm 19 years old and finally want to realise my childhood dream of becoming a commercial pilot. Money is no barrier, I can afford to pay up to £50k
I would look at £120K if money is not a problem. If you are British do the JAA Licence way.
If you have the money then integrated route is for you. i.e Cabair, Oxford or CTC are the big 3 training companies here for JAA students.
Costs more but you have first a lot of the job market, if there is anything out there at all for the next 5 years.
After finishing your Frozen ATPL Licence go back out the USA and do a first officer program. Spend £15K - £20K as a first officer to get some experience. http://www.keylimeair.com/Rates.asp
Then spend another £30K-£50K getting a type rating and 300 hours on the type of aircraft. i.e. see website
http://www.eaglejet.net/
So JAA Frozen integrated route £80K + £15K for living costs for a year and a bit, call it £15K for first officer program and call it £45K for type rating and line training with cost for 300 hours.
In fact my starting figure is now wrong of £120K it adds up to £155K, as what i just start above.
If you want to do the course then there is the modular route, up if you want a job at the end of all this then read and do the above if you have the money you say you have.
Good luck
