CTC have 9 partner airlines??? That's news to me (and I'm half way through my training in NZ)! MyTravel now no longer exist after their take over by Thomas Cook. That leaves easyJet, BA, First Choice, Thomsonfly (I'm listing these two seperately although they have merged as well under the TUI Group but have not stated whether they are to keep operating individually or as one airline yet), Jet2, Monarch and Thomas Cook. However, the statement about CTC primarily feeding easyJet is very true. I do not know the exact figures but I am under the impression that about 70% go to easy, the rest spread around the other airlines. Obviously things change quickly- easy have been going through a period of consolidation as have the charter operators after merging, and BA are going to need a lot of pilots to cope with the deficit that's starting to open up as pilots retire.
As has been said already, do a lot of research before you part with the cash and be very aware of the marketing talk you will get from each training organisation.
