I have colleagues that trained with both BCFT and PAT and highly recommend them both. I also agree with tribekey and Nakata77: mixing it with commercial traffic at a busy airport is advantageous if your aim is to be a professional pilot, as long as it doesn't result in you being frequently held.
I trained with Flightpass at Exeter
www.flightpass.co.uk who were top notch, but I guess that Bournemouth is more suitable geographically for you. Regards,
