Jeju Air in the network the desk measures
Computed on 2026-09-07 from AeroDataBox scheduled route statistics. The desk holds departure schedules for 571 airports, and for the 7C code that yields 59 city pairs across 47 of them. It is a measured sample of the published timetable and not the whole of it. Frequencies move with the season, and a quote is priced on the flights running the day you ask.

The schedule the desk holds carries the 7C code on 59 city pairs, reaching 47 airports in 14 countries and territories. Some of those sectors are flown by Jeju Air and some are sold under its code and flown by a partner, which is how the published timetable states it and how a booking has to be read. 97.9 per cent of those airports sit on Asian time zones, and the next largest block is on Pacific island time zones.
01The longest sector held for the carrier is Denpasar-Bali Island (DPS) to Seoul (ICN) at about 5,272 km, and the shortest is Jeju City (CJU) to Gwangju (KWJ) at about 182 km. 35 of the pairs are under 1,500 km and 1 run past 5,000 km, a medium haul shape that usually joins a Gulf departure at a single interchange. The airport that appears most often on those pairs is Seoul (ICN), on 35 of them, which is 59.3 per cent of everything held under this code.
02The thickest sector under the code is Jeju City (CJU) to Seoul-si (GMP) at about 129.4 movements a day, which across a full day is roughly one every 0.2 hours. On a sector at that cadence a missed departure costs a wait rather than a night. That sector does not touch Seoul (ICN), the airport this code is booked through most often, so the desk treats it as a seat sold under the code rather than flown by the carrier, and confirms the operating airline before it quotes. 31 of the 59 pairs run four or more times a day and 7 run once a day or less. The second figure is the one that matters when a consignment leaves the factory late, because on those sectors the desk will quote a different carrier rather than promise an hour it cannot hold. After Seoul (ICN) the code leans on Busan-si (PUS) on 15, Jeju City (CJU) on 8, Seoul-si (GMP) on 5 pairs respectively, and those are the airports a dispatcher looks at second when the first routing is full.
The sectors that carry the 7C code most often
The 12 sectors the 7C code appears on most often, out of 59. Flights a day is the average daily scheduled movement on the busier of the two directions, as held on 2026-09-07. The schedule lists a code against a sector whether the carrier operates it or sells it, so read this as where the code can be booked. Distances are great circle, computed from the published coordinates of the two airports.
How a courier reaches Seoul from the Gulf
The schedule the desk holds shows no 7C service into a UAE airport, so a courier does not board this carrier in Dubai. The routing is built the other way round: a Gulf carrier takes the first leg to Seoul (ICN), and Jeju Air carries the second.
The first leg, measured. These are the 2 links the desk holds from a UAE gateway into Seoul (ICN), the airport this code is booked through most often.
Night restrictions on the airports the 7C code uses
A hand carry is bought for the hours it saves, and an airport that will not take a movement after a certain hour can spend those hours back. 6 of the 47 airports this code is booked through carry a restriction the desk holds in writing, checked 2026-09-07. Exemptions and seasonal variations exist, and the desk confirms the position with the airport or the carrier before it books.
- Seoul (ICN), night operations. Operates around the clock.
- Taipei (TPE), night operations. Operates around the clock.
- Singapore (SIN), night operations. Operates around the clock.
- Shanghai (PVG), night operations. Operates around the clock.
- Tokyo (NRT), night restrictions. Scheduled movements are limited between 23:00 and 06:00 local; late departures usually route through Haneda instead.
- Denpasar-Bali Island (DPS), nyepi closure. The airport closes for 24 hours once a year for Nyepi, the Balinese day of silence, in March or April; the date moves with the Balinese calendar. No flights operate and nothing moves on the island.
Published lanes the 7C code can carry half of
None of the 346 lanes the site publishes is flown end to end under this code. These 67 are the ones it touches at one end, which is how a routing gets built when no single carrier covers the whole distance: a Gulf carrier takes the first leg and this one finishes it. The lane index holds the rest.
- Seoul to Abu Dhabi, joined at Seoul (ICN), which this code reaches on 35 of its pairs.
- Amsterdam to Seoul, joined at Seoul (ICN), which this code reaches on 35 of its pairs.
- Doha to Seoul, joined at Seoul (ICN), which this code reaches on 35 of its pairs.
- Dubai to Seoul, joined at Seoul (ICN), which this code reaches on 35 of its pairs.
- Seoul to Frankfurt, joined at Seoul (ICN), which this code reaches on 35 of its pairs.
- Helsinki to Seoul, joined at Seoul (ICN), which this code reaches on 35 of its pairs.
- Munich to Seoul, joined at Seoul (ICN), which this code reaches on 35 of its pairs.
- Seoul to Monterrey, joined at Seoul (ICN), which this code reaches on 35 of its pairs.
The countries the 7C code opens
Of the 14 countries and territories reached, 7 are reached at a single airport, which for a courier means one airport of entry and a road leg for everything else in that country. The deepest is Japan with 11 airports on this code. The country desk for South Korea sets out the customs practice, the working hours and the road legs behind these airports.
Japan (11 airports), China (10 airports), South Korea (7 airports), Vietnam (4 airports), Philippines (4 airports), Thailand (2 airports), Taiwan (2 airports), Laos (1 airports), Macau (1 airports), Northern Mariana Islands (1 airports).
