Quick answer: Munich Airport offers Mobility Service Points, a dedicated 'Fastlane' through security and passport control (look for the wheelchair symbol), and an inclusive PRM security checkpoint in Terminal 2.
Getting assistance
Passengers with reduced mobility can use Mobility Service Points to start an assisted-travel process — staff provide wheelchair assistance and guide you through security and to your gate. Terminal 2 has an inclusive checkpoint specifically designed for passengers with reduced mobility, families with children, and anyone needing extra help, with more space and modern scanner technology.
Invisible disabilities
Munich Airport supports the Sunflower Program — a yellow sunflower on a green background that passengers can wear or carry to indicate they may need extra time or support, even when a disability isn't visible.
