Incheon International Airport Access Plan for 60,000 Arrivals

Incheon International Airport is preparing for as many as 60,000 foreign arrivals in a single day on October 2, 2026, around China’s National Day holiday. The Incheon Airport Immigration Office, under the Ministry of Justice, told The Korea Times it will run emergency measures from September 30 through October 3 and put more officers into arrival and departure halls.

If you fly into or out of Seoul through Incheon in late September or early October, the useful work is to add time at immigration, use the earlier departure-hall openings, and treat October 2 as the heaviest foreign-arrival day. Deep Arrival’s airlines hub is the place to keep other operating notes while this window is live. Seoul Economic Daily, citing the same office on September 17, sets the broader special-duty calendar from September 23 through October 11.

October 2 Is the Foreign Arrival Peak

The Korea Times, translating a Hankook Ilbo report, says more than 50,000 foreign nationals a day are expected through Incheon from September 30 to October 3, around China’s October 1 National Day. Over those four days the office expects 198,000 to 220,000 foreign arrivals. That is an average of 49,500 to 55,000 a day, above last year’s 45,640 daily average for September 30 to October 4.

October 2 is the day the office is planning against a 60,000-person foreign-arrival count. Seoul Economic Daily says October 1 could reach 55,000 and October 2 could reach 60,000, compared with a National Day peak of 40,767 foreign arrivals last year. Those figures are forecasts from the immigration office, not a cap on who may enter. They are a reason to land with extra time, not a reason to skip the trip.

Office head Kim Jeong-do said the agency will shift commuting schedules and move people from document inspection and other support desks onto screening lines to avoid gaps. He also said supervisors in the halls will increase and that the office will watch incoming flights in advance to limit crowding. That is a staffing plan. It is not a promise that waits will stay inside a published number of minutes.

Earlier Departure Halls From September 30

Departure halls will open earlier for 12 days from September 30 through October 11, the last day of the Hangeul Day holiday period. The Korea Times lists Terminal 1 Hall No. 2 at 5:30 a.m., Terminal 1 Hall No. 4 at 6 a.m., and Terminal 2 Hall No. 2 at 5 a.m. Seoul Economic Daily describes the same three halls moving 30 minutes earlier than their usual 6 a.m., 6:30 a.m., and 5:30 a.m. openings.

If you have a dawn departure, those 30 minutes are the difference between a closed hall and a usable one. Check which terminal your airline uses. Incheon still splits carriers across Terminal 1 and Terminal 2, and the early openings are hall-specific, not a blanket 5 a.m. unlock of the entire airport. A passenger in the wrong hall at 5:15 a.m. can still be standing in front of a closed door.

Departure staffing also rises from 38 officers to 54 during the emergency window. That helps outbound screening. It does not move your airline’s check-in cutoff, bag drop, or security line. Treat the earlier hall as extra access, then keep the rest of the departure process on the airline’s own clock.

Chuseok Traffic Peaks on September 27

Before China’s holiday, Korea’s Chuseok period loads the same airport with residents leaving and returning. The Korea Times says special Chuseok measures run from September 24 to 27, with daily passenger traffic forecast to hit 245,318 on September 27. Seoul Economic Daily, briefing the same office two days earlier, lists Chuseok measures from September 23 to 27 and the same 245,318 peak on the 27th.

Seoul Economic Daily also splits that Chuseok week: about 131,154 departures on September 24 and about 138,658 arrivals on September 27, with a daily average around 225,899 people, up 6.3 percent from last year. If you are a visitor arriving into that weekend, you are sharing halls with a domestic holiday return, not only with Golden Week tourists. Build more time on September 27 than on a midweek September day.

The office’s longer calendar, per Seoul Economic Daily, runs in three blocks: September 23 to 27 for Chuseok, September 30 to October 5 for China’s National Day and Korea’s National Foundation Day, and October 9 to 11 for Hangeul Day. The four-day emergency staffing window of September 30 to October 3 sits inside the middle block, when foreign arrivals are expected to concentrate.

Immigration Staffing During the Emergency Window

On a normal day the arrival halls run 128 officers. During ordinary special measures, such as other holiday periods, that number is 166. For the four emergency days starting September 30 it rises to 188, a 47 percent increase from the baseline, according to both the Korea Times and Seoul Economic Daily. Departure officers move from 38 to 54, a 42 percent increase.

Those extra people are meant to keep lines moving when foreign arrivals cluster on specific flights. They do not add a new visa class, a new e-gate nationality list, or a new way around inspection. Eligible automated-clearance travelers should still use those lanes if they already qualify. Everyone else should assume a longer foreign-arrivals hall, especially in Terminal 1, which the office says has been carrying more of the foreign inbound load.

Seoul Economic Daily notes that this past summer, from July 22 to August 15, Korean departures fell 4.4 percent while foreign arrivals rose 23.5 percent. Kim said the old pattern of a Korean-outbound summer no longer holds, which is why the office is writing a foreign-arrival plan into a holiday that used to be treated mainly as a Korean departure problem. That is context for the staffing numbers, not a new rule at the counter.

What Travelers Should Recheck Before They Fly

Confirm your terminal, your airline’s bag-drop close, and which departure hall actually opens early. Then add time for immigration on arrival, especially on October 2 and on the Chuseok return of September 27. A connection that looked legal on a quiet Tuesday can fail if the foreign-arrivals hall is holding 50,000 to 60,000 people that day.

Keep hotel pickups and rail tickets flexible on those peak dates. AREX and other city transfers still run, but a late walk-out from immigration will miss a timed train more easily than a taxi queue. If you hold a same-day domestic connection after an international landing, that is the itinerary to unbundle first. This site’s earlier Incheon wait-time note was Terminal 2 weekend security delays, a different screening layer than this immigration holiday plan.
