Where's the thread suggesting people feel the need to sue a UK flying school?
Of the bitching I hear about flying schools a wholly disproportionate of it relates to foreign flying schools. Most often in the US.
Let's keep it correct. The schools we usually hear about are UK flight schools located in the U.S. These schools are often managed by English managers, by the way.
Now, if it is cheaper in the U.S., it's not because they cut back on quality but because operational costs are lower. Just look at the Avgas prices which are more than twice as high in the UK. Landing taxes are inexistent, maintenance costs lower in the US.
Though management seems to be shaky at some of these US-based UK FTO's, the quality of instruction overall looks pretty good.
