What LAX to ICN looks like
The LAX to ICN sector, the carriers on it and the flying time, before anything is promised to anybody.
Los Angeles LAX to Seoul ICN is an ultra long sector of 9,625 km by great circle, flown nonstop 11.3 times a day.
At the cruise speed this site models for 9,625 km, 880 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 12h 06m.
Los Angeles LAX is a major hub in the network held here, 212 scheduled destinations and 826.3 departures a day. Seoul ICN has 165 destinations and 641.2 departures a day.
Seoul runs 17 hours ahead of Los Angeles in January and 16 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 LAX to ICN from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| LAX to ICN | 11.29 | 79 | Air Incheon, Asiana Airlines, Atlas Air, Korean Air, Masair, Perimeter Aviation |
| ICN to LAX | 7.43 | 52 | Air Incheon, Asiana Airlines, Korean Air, Perimeter Aviation |
6 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: LAX to ICN runs 11.3 times a day, the return runs 7.4 times a day, and a round trip has to be planned around the thinner of the two.
At 11.3 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 131 departures a week on LAX 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 12h 06m block time on LAX 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 LAX | 90 min | 1h 30m |
| At LAX before departure | 180 min | 4h 30m |
| LAX to ICN in the air, estimated | 726 min | 16h 36m |
| Formalities at ICN | 90 min | 18h 06m |
| Delivery run in Seoul | 45 min | 18h 51m |
| Door to door | 1,131 min | 18h 51m |
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 LAX to ICN is 18h 51m.
A courier who leaves Los Angeles at 09:00 local is on the ground in Seoul at about 14:06 local and at the door by 16:21 the following day.
Working backwards from a six in the evening handover in Seoul, nothing leaving Los Angeles 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 18h 51m 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. 55 of them join LAX to ICN.
| Connecting at | LAX to hub, flights a day | Hub to ICN, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Anchorage ANC | 1.29 | 1.71 | 9,868 | 13h 54m |
| San Francisco SFO | 44 | 7.71 | 9,628 | 14h 00m |
| Osaka KIX | 1.43 | 42.29 | 10,081 | 14h 12m |
| Seattle SEA | 26.29 | 4.86 | 9,910 | 14h 18m |
| Vancouver YVR | 9.43 | 4 | 9,941 | 14h 21m |
| Tokyo NRT | 5.86 | 49 | 10,011 | 14h 24m |
With 11.3 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.
55 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 9,868 km against the 9,625 km nonstop track and takes about 13h 54m 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 48m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, San Francisco SFO at 14h 00m and Osaka KIX at 14h 12m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
If nothing suitable leaves Los Angeles, San Diego SAN is 176 km away by great circle and carries 123 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 LAX 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.
