I spoke to CTC earlier in the week and they were not sure then, all should hopefully be revealed tomorrow.
Regarding the class thing, I knew one chap who was privately educated from nursery up to 18. His parents point-blank refused to put their house on the line and rightly so, he ended up trying the modular route I think. So, even out of those that could afford it, how many parents would take the risk?
The weird thing in my book is that this setup would not save an airline a lot of money if they are paying the training costs back anyway, so you would think they'd rather take the absolute best as opposed to the best out of a limited few.
