Yeah, go to the USA, take 2 months off work with no loss of earnings, learn to fly in sunny florida, where hotels/car hire/flights/insurance/food etc cost nothing.
Then come back to the UK and wonder why it takes you another 15 hours to learn to talk correctly on the UK radio, navigate around tricky UK airspace, fly on instruments, use a VOR etc, oh and don't forget the JAA checkride/CAA costs
Then sit down when all is done and wonder why all that hassle going to the USA, coming back, doing more flying, paying for more training etc. only saved you £300.
Of course I am being facetious, but seriously, beware, going to the USA isn't always the cheapest/best option. Do you research, and don't believe all those "GET YOUR PPL IN 3 WEEKS FOR $9,999" adverts.
