the problem is that all schools need to be approved.
And also you need to get access to a CPL examiner and also a CAAFU examiner for the IR.
BAe in spain can do the whole lot for you but its intergrated.
In florida you can do cpl course and also flight test (proberly with keywest a moderator on pprune) You can also do the IR training as well but I haven't heard of anyone doing the flight test over there so you would need to return to the UK and get used to our airspace, procedures and RT. Which might be ok if you were an experenced FI in the UK but it might be a bit much if you are a min hours modular student.
And to be honest although there is a big saving in PPL and hour building abroad, there dosn't seem to be the same saving for the proffesional courses compared to UK prices.
