Tips for 4 hr Connections
Budget extra time for immigration if arriving internationally, as queues can be slow during peak evening hours.
Domestic-to-domestic connections are the smoothest, using a single shared security zone.
If connecting from international to domestic, be prepared to collect and recheck baggage after customs clearance.
Signage in the terminal is decent but confirm your gate area early, as domestic and international gates are on opposite ends of the building.
Avoid tight connections on international itineraries, since CCU is not built for rapid international transfers.
Busyness — Connection Risk

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.
Getting Between Concourses
The domestic and international sections sit within the same integrated terminal building, connected by a long internal concourse walkway. International arriving passengers must clear immigration and customs before any onward connection, and international departures require a separate security and document check area, so there is no true 'sterile corridor' shortcut between the two sides.
