Thanks for the info Scagrams and Krapouk.
Scagrams, did you book by yourself or through BAA?
Actually I was thinking about what would be the best date to start, here's my thoughts:
On one side of course it would be better not to be in a rush. I still myself have to do the assessment so starting in December or February would allow for less pressure.
On the other side I also think that Wizz Air will offer a position on a first come first served basis, therefore starting as soon as possible would put you in a better position than those starting later.
At this moment Wizz Air seems to be in need for pilots, but when they'll feel they'll have enough (consider also those that will finish CTC and CEFA courses) they could offer worse conditions to the latest arrived, i.e. they could sponsor the TR to the first courses and not to the latest.
What's your opinion?
