Bart,
I was actually speaking of airports that require re-screening even if the passenger stays in a sterile area. For example, passengers transiting in London, Brussels, Copenhagen, Oslo, Paris, Tokyo, and many other points must be rescreened.

These passengers do not have access to checked baggage and do not exit the sterile area.

The airports just require that anyone transiting in their airport go through security screening.

In some cases, such as Amsterdam, Singapore, and Vienna, the checkpoints are at the gates themselves, so an "express van" wouldn't make a difference. The passengers would be rescreened at their departure gate.

But what about airports with centralized screening? Are these passengers exempt from this procedure?
