Hi Variablepitch
I've just been on selection with CTC and I applied in October. I think that the May estimate is probably accurate, because they seem very busy.
The hold pool has 1 person in it at the moment. We asked that same question and 5 pilots had just been taken on by MyTravel that day. (I think it was them)
CTC are a very well run and professional outfit from what i have seen, and the guys we talked to who were on the course spoke highly of the course and instructors.
good luck with that selection.
Best regards
