Do you need security again on Munich layover?

Munich or Paris layover: will you need security again?

In most European transfer scenarios, whether you face security screening again depends on how you are routed and whether you are changing terminals or entering a new airside area.

A key factor is the type of connection:

• Landside-to-airside changes (e.g., you leave the secured area): If your layover requires immigration/customs or you go through passport control again, you’ll typically be treated like a new arrival and will need to clear security before boarding the onward flight.
• Staying airside the whole time: If you remain in the secured transfer zone and your onward gate is accessible without re-entering the airport security area, you usually do not face a full security re-screen.

Some airports also handle certain connections by routing passengers to a shared transit corridor, while other transfers—especially involving separate tickets, long gaps, or different terminals—can create additional screening steps.

The practical takeaway: check your itinerary and airport map for terminal and transfer-zone instructions, and confirm whether both flights are on the same booking. If you’re unsure, it’s safest to build in extra time in case you do need to re-clear security.

Because airports vary by operator and layout, the only way to be certain for your exact transfer is to follow the signs at the time of arrival and ask at the transfer desk, but in general, leaving the secure area is what triggers the need for security again.

If you share your airports, terminals, and whether the flights are booked together or separately, you can often predict the likely flow more accurately.
