When I change planes do I have to go through security again?
If you are booked on Germanwings flights changing planes in Berlin or Hanover, you have to go through security again.
If you are booked on Germanwings flights changing planes in Cologne or Stuttgart, you have to go through security again if you are arriving from a Non-Schengen* and/or non-EU country. In Cologne and Stuttgart the security check is in the same area as the departure gates.
Please make sure you are aware of the current conditions applicable to conditions applicable to hand baggage.
*You can find a list of Schengen countries on the European Commission’s homepage.
