What ORD to ICN looks like
The ORD to ICN sector, the carriers on it and the flying time, before anything is promised to anybody.
Chicago ORD to Seoul ICN is an ultra long sector of 10,519 km by great circle, flown nonstop 4.7 times a day.
At the cruise speed this site models for 10,519 km, 880 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 13h 10m.
Chicago ORD is a major hub in the network held here, 295 scheduled destinations and 1,461 departures a day. Seoul ICN has 165 destinations and 641.2 departures a day.
Seoul runs 15 hours ahead of Chicago in January and 14 hours ahead in July, because the two ends do not change their clocks together.
The pair sits between the Americas and Asia Pacific, a corridor where the site already publishes 16 written lanes that go into customs and ground detail this page does not.
Who flies the sector, and how often
Average daily frequencies on ORD to ICN from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| ORD to ICN | 4.71 | 33 | Atlas Air, Korean Air, Western Global |
| ICN to ORD | 1.14 | 8 | Korean Air |
3 carriers are recorded on the sector, so a missed departure is normally a rebooking rather than a lost day.
The two directions are not level: ORD to ICN runs 4.7 times a day, the return runs about once a day, and a round trip has to be planned around the thinner of the two.
At 4.7 times a day there is usually another departure within a few hours, which is what makes a same day booking on this pair realistic.
Between them the two directions put about 40.9 departures a week on ORD to ICN, which is the number that decides whether a seat can be found today or on Thursday.
The clock from collection to signature
The same ground timings the route calculator starts from, applied to the 13h 10m block time on ORD to ICN. Change any of them in the tool further down and the total moves with them.
| Stage | Allowed | Elapsed |
|---|---|---|
| Collection and the run to ORD | 90 min | 1h 30m |
| At ORD before departure | 180 min | 4h 30m |
| ORD to ICN in the air, estimated | 790 min | 17h 40m |
| Formalities at ICN | 90 min | 19h 10m |
| Delivery run in Seoul | 45 min | 19h 55m |
| Door to door | 1,195 min | 19h 55m |
On the desk standard ground timings, ninety minutes to collect and reach the airport, three hours at the airport before departure, ninety minutes of arrival formalities and a forty five minute delivery run, the door to door figure for ORD to ICN is 19h 55m.
A courier who leaves Chicago at 09:00 local is on the ground in Seoul at about 13:10 local and at the door by 15:25 the following day.
Working backwards from a six in the evening handover in Seoul, nothing leaving Chicago inside a normal working day arrives in time, so this pair is an overnight and a next morning delivery rather than a same day one.
At 19h 55m the mission is past the sixteen hour duty day a single courier is planned against, so it is quoted with a rest at the far end or with a second courier, and never as a turnaround.
When the nonstop does not work
Every airport that joins the two ends, ranked by when they land, among the ones whose weaker leg is dependable enough to plan on. Connection time is allowed for the size of the hub. 52 of them join ORD to ICN.
| Connecting at | ORD to hub, flights a day | Hub to ICN, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Anchorage ANC | 8.86 | 1.71 | 10,666 | 14h 51m |
| Minneapolis MSP | 22.14 | 1.14 | 10,567 | 15h 07m |
| Calgary YYC | 5.86 | 1 | 10,766 | 15h 22m |
| Detroit DTW | 21.43 | 1.29 | 11,031 | 15h 38m |
| Osaka KIX | 0.86 | 42.29 | 11,309 | 15h 41m |
| Vancouver YVR | 5.86 | 4 | 11,031 | 15h 45m |
With 4.7 times a day on the nonstop, a connection here is a disruption plan rather than a routing, and it is listed because a closed runway or a cancellation wave is exactly when nobody has time to work it out.
52 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Anchorage ANC, where the weaker of the two legs still runs about once a day.
Through ANC the routing covers 10,666 km against the 10,519 km nonstop track and takes about 14h 51m in the air and on the ground at the hub, allowing 60 minutes to connect at an airport of that size.
That is only 1h 41m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Minneapolis MSP at 15h 07m and Calgary YYC at 15h 22m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
If nothing suitable leaves Chicago, Chicago MDW is 25 km away by great circle and carries 208 scheduled destinations of its own, which is usually a shorter road transfer than a lost day.

Where this came from, and where to look next
- Carriers and frequencies: AeroDataBox scheduled route statistics, retrieved 2026-09-07. Average daily flights, not a timetable.
- Distances: great circle from published coordinates. They read short against a flown track, which is why the block time above applies a factor to them.
- Block and connection times: the same model the route calculator lower down this page runs, at the same rounding.
- Restrictions: the airport notes file, checked 2026-09-07.
- Industrial sites: public company information. Nothing here says or implies that any company named is a customer of any courier operator.
Who publishes this. OnBoard Courier is a placement desk in Dubai. An assignment is carried out by a vetted partner operator, with the desk as the single point of contact from the quote to the signature. This page exists because our own dispatchers need the answer for ORD to ICN in the twenty minutes before a promise is made, and a reference only one operator can read is not a reference. Free to read, quote and cite. Found an error? Tell us and we will correct it.
If you need something moved rather than looked up, the desk prices a hand carry in fifteen minutes.
