Well this is a bit confusing, EPST now offers the course in cooperation with OAA, why would someone even go to EPST in the first place? Also NLS is as far as I know the same as OAA oxford, and follow the same program for the integrated course, at the same cost. CAE in my opinion are trying to create a monopoly by buying the best flight schools in Europe, in the end if you don't pay 100k Euros, then you have very little chances of getting employed after you finish.
CTC, OAA, and FTE, they are the big players and anyone who wants to increase their chances of getting a job after they finnish must get their training with these boys.
