Whilst not wishing to fuel unfounded speculation, my university started an airline focused degree course and were looking to partner with a flight school, after inspecting and having meetings with ctc i was told they were not impressed at all. They wouldn't go into specifics with me but I could sense a very negative reaction from whatever dealings they had with them.
Another thing is my former airline with whom I had an office based role were looking to relaunch their cadet programme, they looked at ctc, and they had just the same negative reaction after inspections and meetings. Of course I wasn't gonna be told what was so wrong ...
