What LHR to ICN looks like
The LHR to ICN sector, the carriers on it and the flying time, before anything is promised to anybody.
London LHR to Seoul ICN is an ultra long sector of 8,861 km by great circle, flown nonstop 3.4 times a day.
At the cruise speed this site models for 8,861 km, 880 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 11h 10m.
London LHR is a major hub in the network held here, 212 scheduled destinations and 758.3 departures a day. Seoul ICN has 165 destinations and 641.2 departures a day.
Seoul runs 9 hours ahead of London in January and 8 hours ahead in July, because the two ends do not change their clocks together.
The pair sits between Asia Pacific and Europe, a corridor where the site already publishes 46 written lanes that go into customs and ground detail this page does not.
Who flies the sector, and how often
Average daily frequencies on LHR to ICN from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| LHR to ICN | 3.43 | 24 | Asiana Airlines, Korean Air, Virgin Atlantic |
| ICN to LHR | 3.43 | 24 | Asiana Airlines, Korean Air, Virgin Atlantic |
3 carriers are recorded on the sector, so a missed departure is normally a rebooking rather than a lost day.
At 3.4 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 48 departures a week on LHR 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 11h 10m block time on LHR 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 LHR | 90 min | 1h 30m |
| At LHR before departure | 180 min | 4h 30m |
| LHR to ICN in the air, estimated | 670 min | 15h 40m |
| Formalities at ICN | 90 min | 17h 10m |
| Delivery run in Seoul | 45 min | 17h 55m |
| Door to door | 1,075 min | 17h 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 LHR to ICN is 17h 55m.
A courier who leaves London at 09:00 local is on the ground in Seoul at about 05:10 local and at the door by 07:25 the following day.
Working backwards from a six in the evening handover in Seoul, nothing leaving London 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 17h 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. 66 of them join LHR to ICN.
| Connecting at | LHR to hub, flights a day | Hub to ICN, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Copenhagen CPH | 10.57 | 1 | 8,904 | 13h 03m |
| Helsinki HEL | 4.57 | 1.14 | 8,880 | 13h 05m |
| Beijing PKX | 1.14 | 3.43 | 9,098 | 13h 16m |
| Amsterdam AMS | 16.14 | 2 | 8,922 | 13h 21m |
| Warsaw WAW | 6.57 | 1 | 9,196 | 13h 26m |
| Beijing PEK | 2.29 | 10.29 | 9,056 | 13h 28m |
With 3.4 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.
66 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Copenhagen CPH, where the weaker of the two legs still runs about once a day.
Through CPH the routing covers 8,904 km against the 8,861 km nonstop track and takes about 13h 03m in the air and on the ground at the hub, allowing 75 minutes to connect at an airport of that size.
That is only 1h 53m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Helsinki HEL at 13h 05m and Beijing PKX at 13h 16m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
If nothing suitable leaves London, London LCY is 36 km away by great circle and carries 38 scheduled destinations of its own, which is usually a shorter road transfer than a lost day.
Restricted hours at either end
Widely documented operating restrictions, checked 2026-09-07. Exemptions and seasonal variations exist, so confirm with the carrier before relying on any of them.
London LHR is shut to scheduled movements between 23:30 and 06:00 local, so a collection in London that runs late does not simply catch a later flight, it waits for the morning and loses a working day in Seoul.
London LHR, night restrictions: A night quota system limits movements between 23:30 and 06:00 local. Very few scheduled departures in that window.
Seoul ICN, night operations: Operates around the clock.

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 LHR 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.
