AD PLACEMENT — CONTEXTUAL
Since the airport is a single small terminal, you rarely need more than 10 minutes to walk gate-to-gate, even at opposite ends.
If connecting between two Schengen flights, there's no passport control, so security re-clearance (if required) is the main time factor.
Flight frequencies to many destinations are low, so a missed connection can mean waiting several hours or overnight for the next flight.
The single security checkpoint can back up during the morning bank of departures around 6-9am, so build in extra time then.
There are limited lounge and dining options, so don't expect much to do during a long layover beyond a couple of cafés and a small duty-free area.

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 gates are located within one compact terminal building, reached on foot via a single central departure hall with two short gate piers. There is no shuttle or train — the longest walk from one end of the terminal to the other is under 10 minutes. Passengers connecting from a non-Schengen flight (e.g. UK, or a long-haul arrival) to a Schengen flight must clear passport control and may need to re-clear security if arriving from outside the Schengen security zone.
