Tips for 40 min Connections
Sendai's small terminal means walking between domestic and international sections takes only a few minutes.
International connections require full immigration and customs clearance, so budget extra time even though queues are usually short.
There are few flights per day on international routes (mainly Seoul and Taipei), so a missed connection can mean a long wait until the next departure.
Domestic transfers are simple since JAL and ANA operate from the same compact check-in hall.
The airport has limited dining and lounge options, so don't expect much to do during a long layover.
