Come off it !
There are just places in the UK just as cheap if not cheaper!!
Whatever you like, or spend, some know-it-all says you could get it cheaper.
I've no idea how much OBA charge and what's included e.g. accomodation but they always seem very good value- when comparing like with like. However, I'm sure that Redneck Air Center in Hillbilly County and many other dubious operations in the US will be cheaper. However, the suggestion that places in the UK are cheaper is both proposterous and unsupported or are you referring to gliding or somewhere using stolen fuel?
