With seemingly more and more UK airlines using CTC as their source of new recruits it is only going to get harder and harder to change airlines. When they all use CTC you will effectively be stuck in the airline you first get into because all the other airlines will only want a new batch of 21yr old CTC cadets. Slightly ironic that a CTC student ends up stuck in a job thats not what they want but are prevented from moving by CTC cadets. Sadly those with big cheque books have screwed this industry.
