The recommendation is to wait in the cell phone waiting area directly west of the airport ( I don't recall the side street name, but look for the signs) until the passenger calls to let you know they are ready to be picked up. There are too many variables to give a time, where they are seated on the plane, checked baggage ECT. If you pull up to the pick up zone and are there for more than a couple of minutes, the police will require you to leave. Hope this helps.
Makes sense, agreed
