X3K5,
You claim that we don't have any idea how expensive it is to run a flight school. Well that is NOT THE CUSTOMERS PROBLEM (please also note the word 'customer'). My question/proposal to you is do you have any idea how expensive the cost base of running a school should actually be? After all numerous other schools around the globe can achieve the same if not a better standard than OAT for a cheaper price. Like for example over inflated Italian designer clothes, OAT is more brand name than practical outlay of a truely elite form of training.
I doubt very much whether OAT is value for money and if other training providers worldwide are inferior then everyone would flock to OAT. The fact is that other students go on to become equally if not better pilots than OAT graduates, there's nothing exclusive about OAT.
