AD PLACEMENT — CONTEXTUAL
Double-check your flight is even scheduled that day, as many CJJ international routes operate only a few days per week.
Because there's no dedicated transit zone, budget time to reclear security if moving between domestic and international areas.
The terminal is small enough that a missed gate announcement is unlikely, but flight information displays can be sparse — ask staff directly if unsure.
Arrive early for international departures since check-in counters open a limited window before flight time and can queue up quickly during peak morning and evening banks.
If your connection involves a long layover, note that airport dining and amenities are very limited, so consider planning a meal beforehand.

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.
CJJ has a single small passenger terminal with domestic and international processing areas under one roof, connected by a short indoor walk of a few minutes. International arrivals must clear immigration and customs, and connecting to another international or domestic flight requires a fresh security screening since there is no sterile transit corridor.
