AD PLACEMENT — CONTEXTUAL
Since all terminals are interconnected, you rarely need more than a 5-10 minute walk between any two gates.
If arriving from a non-Schengen flight, budget extra time for passport control, which can back up during peak morning and evening waves.
Lufthansa and Eurowings flights dominate the schedule, so most connections are same-terminal and straightforward.
The airport is small enough that signage and gate-to-gate distances are rarely a source of delay, unlike larger European hubs.
Avoid tight connections around 7-9am and 5-7pm when the airport's few daily banks of flights cluster.

Low risk
Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
All terminals sit in a single connected building arranged in a horseshoe shape around the central area, so passengers walk directly between gates with no shuttle or train required. Passengers arriving from non-Schengen flights (e.g., from the UK or intercontinental routes) must clear passport control and sometimes a secondary security check before entering the Schengen-only zones.
