FL240,
Number of sectors is nearly the same as elswhere - around 28 I believe, but the thing is, for now, they pay double tax there - full UK (since it is Wizz Air UK) and full Swiss (since it is Wizz Air) income tax. I am sure it will be sorted sooner or later but it might take months. I heard there are those who currently pay nearly 70%...
I was considering moving to LTN myself but I will wait untill things are sorted out.
I am quite impressed that you were offered LTN because it is only 1 AC over there and the base if full, plus there are plenty of people on the waiting list for the next 2 AC. On the other hand, Wizz is desperate for people so they might put you in front of the queue.
Ask around during your line training and decide then if you do not like LTN. When it comes to an end you can be assigned any avaliable base you prefer.
