T'way 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 TW code that yields 51 city pairs across 41 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 TW code on 51 city pairs, reaching 41 airports in 20 countries and territories. Some of those sectors are flown by T'way 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. 80.5 per cent of those airports sit on Asian time zones, and the next largest block is on European time zones.
01The longest sector held for the carrier is Barcelona (BCN) to Seoul (ICN) at about 9,594 km, and the shortest is Jeju City (CJU) to Gwangju (KWJ) at about 182 km. 9 of the 51 pairs run past 5,000 km, so the carrier carries a courier across a continent on some sectors and shuttles on the rest. The airport that appears most often on those pairs is Seoul (ICN), on 23 of them, which is 45.1 per cent of everything held under this code.
02The thickest sector under the code is Jeju City (CJU) to Daegu-si (TAE) at about 19.4 movements a day, which across a full day is roughly one every 1.2 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. 19 of the 51 pairs run four or more times a day and 8 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 Jeju City (CJU) on 8, Busan-si (PUS) on 7, Osaka (KIX) on 6 pairs respectively, and those are the airports a dispatcher looks at second when the first routing is full.
The sectors that carry the TW code most often
The 12 sectors the TW code appears on most often, out of 51. 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 TW 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 T'way 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 TW 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. 9 of the 41 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.
- Tokyo (NRT), night restrictions. Scheduled movements are limited between 23:00 and 06:00 local; late departures usually route through Haneda instead.
- Taipei (TPE), night operations. Operates around the clock.
- Singapore (SIN), night operations. Operates around the clock.
- Frankfurt-am-Main (FRA), night restrictions. No scheduled take offs or landings between 23:00 and 05:00 local. A late evening departure that slips past 23:00 does not go until morning.
- Sydney (SYD), curfew. Curfew between 23:00 and 06:00 local. Jet departures are not permitted in that window and a late departure waits until morning.
Published lanes that carry the TW code
The site publishes a page for 346 courier lanes. T'way Air appears in the schedule on one of them, and the one it flies most is Seoul to Frankfurt at about 4.4 movements a day. That overlap is the honest test of whether a carrier is useful to this desk rather than merely famous.
The countries the TW code opens
Of the 20 countries and territories reached, 14 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 7 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 (7 airports), South Korea (7 airports), China (5 airports), Taiwan (4 airports), Vietnam (2 airports), Indonesia (2 airports), Macau (1 airports), Germany (1 airports), Canada (1 airports), Singapore (1 airports).
