About the Tokyo (NRT) to Seoul (ICN) shipping route by air

Flight time is about 2 h 24 min at 800 km/h block speed. On a short route like this one, trucking under an air waybill (road feeder service) is common, and the cargo may never board a plane. Door to door air freight transit time is usually 1 to 3 days longer than the flight because of acceptance, security screening, customs and handling at both airports.
In the week we checked there were 10 flights between NRT and ICN, 4 of them on freighters, operated by Korean Air.
Air freight rates are charged per kilogram of chargeable weight: the higher of the actual weight and the volume weight (length x width x height in cm divided by 6,000). Light, bulky cargo pays for space, so compact packing on Tokyo to Seoul saves money. The shipment crosses from Japan into South Korea, so export and import customs clearance are part of the lead time.
Among 69 routes from Tokyo (NRT) in this directory, Seoul (ICN) is the 2nd shortest by flight distance. Shorter flights from Tokyo: Osaka (516 km).
