Quite the contary.
CTC, to my knowledge recruit for quite a few airlines such as easyjet, JMC, Monach etc.
If you apply to CTC and are unsuccessful then all these airlines will not recruit you, (until you have a low more experience). Therefore Your chances of employment are considerably less.
Also if the airlines had to recruit directly the competition to recruit low houred pilots would increase, the airlines would have to offer cadet pilots more (type rating, better wages, pension etc.). Instead they all go to one "pool" and save money (who can blame them).
Its difficult because from it does look like everyone gains, the airline, the pilot and CTC but it's the industry as a whole that suffers partically the overall recruitment of cadet pilots.
I don't condone anyone for paying into these schemes, including the ryan air 18K type rating bond. But the more people that do the longer the situation will remain.
