Just to give my view...
I used Flight accademy last year/early this year to hour build. The planes are of a great standard, the newest I have ever flown. Your bookings are booked via an online system, so once its booked, you generally dont get moved around for other people, only if a/c goes tech which cant be predicted. Each member can book only 3 confirmed slots so everyone gets a fair chance, you can book as many slots as you like, once you use a confirmed slot up then your next provisional booking becomes confirmed.
I found this a brilliant cost effective way to build my hours, with safe and well maintained aircraft. I flew the PA28's from both Blackpool and Barton.
I would highly recommend this place to anyone, go and visit them, see what you think
