How does check-in and passport control work at Cam Ranh Airport (Nha Trang) — separate lines per flight or shared queues?

On Aug 9, around 100 people from two flights piled up at passport control at the same time — only one booth was open for exit, creating a long queue.

There's a paid on-site option for priority check-in — about 3000 RUB per person to register before the general queue starts.

First-row seats for both outbound and return flights were pre-purchased through travel retail — total came to about 20,000 RUB.

Each flight has its own separate check-in counter, but passport control and security screening before departure share one common queue for all passengers.
