Money is no barrier, I can afford to pay up to £50k (although I'm sure in the USA it can't be as much as that).
Interesting .... You're ready to blow £50k on something you haven't fully researched. I hope your £50k can stretch further than that too.
If you go to the US and blow $75k at EAA on the
'Cleared Direct' course, which I think is pretty good considering you get to fly state of the art aircraft and not a beaten up old aircraft that some other schools use.
First tip I have picked up is, if you're going to the US to do your flight training go to an FAA school and do the FAA licences, then when you get back here to the UK convert both the CPL and IR to a JAA licence/rating.
If you think £50k is going to cover all that then you may be kidding yourself though, if however you stick to doing the JAA licences/ratings in the UK it might cost you around the same amount as 'FAA and then converting leaving you with both FAA & JAA licences'.
After spending all this money you might find your just another 250hr fATPL holder looking for a jet job, so you might be at a big advantage if you had 1,000+hrs from banner towing/instructing/glider tug/bush pilot etc. But you might find it's an uneven playing field when your looking for a jet job with no Type Rating (£20k) and if you did have the TR you might be up against a pilot who has a 737 Type Rating & 500hrs line training.
So the list is endless and so will the bills to pay for it all, so if money is no barrier and you're a 19 year old with £120k sitting in the bank then keep in touch
As for the best place to start off look
here.
If you can get on a CTC course (seen
here) then that will be your safest and best bet into the airlines, but be aware I think the statistics show that only 2% of candidates make it to the course ... on the flip side I've not heard of any CTC student not getting a job with the airlines.
Failing that
Oxford aviation and
Flight Training Europe will happily take your £50k and any spare change you have to the sum of £25/£30k you have under the sofa.
Good luck.
