Seoul (ICN) to Hanoi (HAN) shipping route.

Seoul to Hanoi by air: flight distance 2,818 km, heading south west from South Korea to Vietnam. The shortest line over the globe is 2,684 km, and real airways add the rest.

Flight time is about 4 h 18 min at 800 km/h block speed. Most cargo on this distance flies nonstop, in a freighter or in the belly of a passenger aircraft. 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 5 flights between ICN and HAN, 3 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 Seoul to Hanoi saves money. The shipment crosses from South Korea into Vietnam, so export and import customs clearance are part of the lead time.

Among 69 routes from Seoul (ICN) in this directory, Hanoi (HAN) is the 13th shortest by flight distance. Shorter flights from Seoul: Chengdu (2,316 km), Hong Kong (2,173 km) and Shenzhen (2,147 km).
