Incheon Airport Rail Strike Could Cut 106 Daily Services

By Grace Kim

A planned one-day union strike on November 13, 2026, could remove 106 weekday trains from Incheon International Airport's rail timetable. Airport Railroad Co., known as AREX, confirmed its contingency plan on November 6, after outlining how it would manage passenger demand if the industrial action proceeds.

The South Korean operator intends to maintain all 56 daily Airport Express Train services between the airport and Seoul Station. The 56-service plan protects the principal nonstop connection in the published timetable, but it remains a contingency rather than proof that the strike has occurred or every November 13 service has run.

How much rail capacity will remain?

AREX's stated commitment is to “maintain 100% of its normal express train schedule during the November 13 industrial action.” The company plans to deploy essential personnel and available staff to protect that direct link, with additional passenger-guidance and safety personnel assigned to managing queues and platform congestion at major stations.

The express figures come from a contingency timetable, not a completed operating day. Express passengers are expected to face fewer timetable changes, although AREX continues preparing crowd-management arrangements at major stations.

Where do the 106 cuts fall?

Regular all-stop services would fall from 369 per day to 263, representing 71.3% of normal operations and 106 fewer trains. That loss equals 28.7% of the regular all-stop timetable. The combined weekday timetable would decline from 425 trains to 319, or approximately 75.1% of usual service, if AREX implements the plan without further changes.

The plan does not shut down airport rail. It would remove 106 services from one timetable while protecting the nonstop link, leaving the all-stop pattern to carry the full disruption. In practical terms, passengers retain three of every four weekday trains, but not the full all-stop schedule.

AREX plans to keep regular all-stop frequency close to normal levels from 7 a.m. to 9 a.m. and from 6 p.m. to 8 p.m. Outside those four commuting hours, passengers may face longer waits and increased crowding.

Who bears the connection risk?

AREX's all-stop route links Incheon International Airport with several intermediate stations before reaching Seoul Station. The 106-service reduction therefore affects passengers bound for areas of Seoul and connecting stations, not only those using the nonstop airport express. For airport-based itineraries, the disruption is tied to the connecting pattern rather than the direct Seoul leg.

All 56 express services are expected to operate between Incheon International Airport and Seoul Station, subject to the contingency assumptions. AREX advises travellers with early-morning, late-evening or time-sensitive flights to check the latest timetable before departure.

The 56-service express schedule protects the direct airport-to-Seoul leg, but it does not restore capacity on the connecting route. Under AREX's plan, a passenger relying on an all-stop train outside the two protected peak windows may face a longer wait and more crowding.

What can still change?

AREX will publish updated train information through its website, social media channels and station announcements. Those notices will carry the operational detail travellers need before choosing a train or connecting to a flight.

AREX continues negotiations with the union over staffing levels, pay and career progression. The talks cover the staffing, pay and progression issues behind the planned action, while the emergency timetable reflects the company's current contingency assumptions.

The November 13 strike remains planned, and AREX must confirm any final timetable change, postponement or cancellation. The company has not confirmed that the action took place or that every November 13 service has been completed.

Until AREX confirms the outcome, passengers should treat 319 weekday trains as a planning figure, not a service record. The 56 airport express trains remain scheduled, while the 106-service all-stop reduction carries the larger operational risk. The next firm service count will come when AREX confirms whether the November 13 action proceeds, changes or is cancelled.
