Chief,
Well done on passing the selection, and not having to sit in a simulator!
Experiences of CTC can be good, bad, and so-so. It is always useful for people to hear all sides to the story, from those who are about to train, to those who are actually airline pilots. There's nothing wrong with views which paint a negative view of CTC so to help people to make an informed decision. In fairness to the recent replies on here, the emphasis has been on timing and training, and the impact to placement if airlines continue on a summer-only contract. Most agree that the standard of training is good, certainly in the piston stages of flight training.
Jerez use that Spanish bank as well, and I don't think a requirement is to speak Spanish. Be aware that your loan will be in Euros, and of course, CTCs bill is in UK pounds!
