Thanks guys actually I happened to see Wizz Air minibuses with "crew car" written on it, but then on the pilots' recruitment they didn't mention it and actually wrote that you have to present yourself to work by your own.
I saw those crew cars in the city also during daytime, are you sure it is only before 6 and after 22, perhaps they do the pick ups if crew members pay a monthly fee?
Captplaystation what "CC in BT" stands for?
