Domestic
I have not arrived on a domestic flight at this airport

International
On landing you walk up the airbridge and into the terminal building. It's a short walk down to the immigration desks and then through to the large baggage reclaim hall. From baggage reclaim it's a short walk past customs officials out into the tiny arrivals area, which looks like it's just a shelter that's been bolted onto the outside of the building

Immigration was quick and efficient

The baggage reclaim hall is large but quite dark.

Rather than having channels there were just customs officials standing around near the exit from baggage reclaim

There are regular buses from the airport to the city centre taking about 25 minutes to make the journey

I have not flown domestically from this airport

International
The check-in area is quite large and light, but it's arranged in a semi-circle and on very busy days I could see it quickly getting very full with lines getting muddled as they approach the centre of the area. Once through security you are into the departures area which is a long corridor above the gates. For non-Schengen departures you have to pass through passport control at the top of a slope leading down into the gate room. The gate rooms themselves are quire small and not capable of holding a full planes worth of customers.

There is nothing landside, and a couple of bar/cafes airside
