If true, that is disgusting!
Although OAA are well known for being expensive anyway; I originally trained in what's now Serbia, the course costs last year were about €50k (less than £40k) for CPL, IR and MCC/JOC. How OAA can charge more than double for that is beyond me, but there we are.....
A lot of the trainees from there are now flying for Wizz, Air Malta, Turkish etc, so by no means a Mickey Mouse outfit.
