Don't be fooled by UKFT's misleading marketing. They are not approved to provide training for the JAA PPL. What you will get from UKFT is a FAA PPL, just the same as at any other US flight school. If you want to train for a JAA licence, you must go to a school approved by the JAA. In the US, the approved schools are:
Atlantic Flight Training - Sanford, FL
Comed Flight Training - Ramona, CA
European Flight Training - Fort Pierce, FL
International Flight Training Academy - Stuart, FL
Naples Air Center - Naples, FL
Cabair (Orlando Flight Training) - Kissimmee, FL
There is one other but we're not allowed to mention it on this Forum because the only comments it ever gets are negative.
