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.
