In most airports which have Fast Track for security it is free to Biz Class pax either for all or specific airlines.

I will be flying in AZ Biz, connecting in FCO, and will have to go through Security there (in both directions). I googled FCO Fast Track and it only told me that it is available for 5 Euros. I saw no mention of Biz pax getting it for free. It also gave very little information about it, but gave me an e-mail address to ask about it.

I wrote on Tuesday and, of course, received no answer.

Can anyone here tell me if Biz gets it without charge or, if not, where I can pay the 5 Euros? Also, is it fast enough to make it worthwhile?
