Can't imagine you'd be abe to get a fATPL for less than £30k
OBA will get you a fATPL for £26k but you'll still need to convert the FAA IR to a JAA IR back in the EU costing around £5k.
OFT will offer you a fATPL for £19k again with a £5k IR conversion in the EU.
But I'm hearing more and more about hidden costs in the US, add the conversion costs and there's very little difference in costs between the UK and US. US can offer better weather and cheaper fuel compared to the UK.
I'm still scratching my head on this one.
Egnatia will give you a complete JAA fATPL for just over £30k but you might want to research this place before going there - kinda put me off.
Most people who have completed the modular route are looking at receipts that amount to around £45k done in the US or UK.
