My wife and I will soon fly AMS-DUS-AMS as positioning flight for further International flights from AMS. Therefore we will return immediately with the same KL plane and have very limited transfer time. We travel with hand luggage only and will have our boarding passes!

I have used DUS a lot in the past and know that the bus will bring you from the KL plane to the terminal and you can use the stairs to go directly into the Airside of the terminal which ensured a very quick transfer.

I now read on the official site of DUS Airport that extra Security Checks are implemented without giving further details.

Can anybody tell me what the current procedure is for Schengen to Schengen transfers at DUS?
