KL International Airport exceeds service quality targets in General Aviation Posted December 23, 2018 · Report reply There is no security screening after immigration at MTB. That is customs screening - but I see your point of it being almost pointless. It is so very easy to avoid it altogether if one makes the effort. Just want to ask. 1. What is the intention of Customs screen all pax for at KLIA? Is it for tax purpose? 2. Does other International airport "BKI,KCH,PEN,etc..." have the first screening process at those airport?
