I do think Fast Track is painfully slow. They only have a small area and use the old style machines so everything has to come out, requiring 2-3 bins per person. They can only hold about 6-8 bins on the belt so can process only a couple of people at a time.
The X-Ray machine is the open type where you put your hands up and feet on cut-outs so is pretty slow in comparison to a metal detector of the old arch type.
