I'm booked on a JAR PPL course at Orlando Flight Training in Florida in April next year at a cost of $4495 (on the C152 or Katana, of which I've selected the latter).
Check out
www.flyorlandoflorida.com for info.
This works out at £3395 on current exchange rates (typical, it was £3k when I booked and the rate has worsened!). Don't forget air tickets to MCO (ours cost £324 with Delta via Atlanta) and living expenses. The course includes accommodation but I've booked a villa. I would still think you can get the whole course, flights and expenses for about £4.5k all in - not necessarily a big saving but considering current weather in the UK it'll probably be a year (and £7k) before the magic licence is achievable. Incidentally, if anyone out there has been to OFT at Kissimmee, any advice or info. you have would be appreciated.
