Daily Schedule and Terminal Information
The airport bus typically departs from Sejong starting early in the morning, with the first bus leaving around 3:40 AM and the last departure scheduled at approximately 4:30 PM.
Arrival times at Incheon Airport Terminal 1 usually range from early morning to early evening, depending on traffic. Because schedules may change due to seasonality or road conditions, checking the most up-to-date timetable before departure is essential.
Incheon Airport operates two terminals, Terminal 1 and Terminal 2, and airlines are assigned to specific terminals. Confirming your flight’s terminal in advance helps avoid confusion when selecting your bus.
Terminal 1 is commonly used by airlines such as Asiana Airlines, Jeju Air, and T’way Air, while Terminal 2 serves carriers including Korean Air, Delta, Air France, KLM, and Jin Air.
Why Real-Time Traffic Checks Matter
Road conditions can vary significantly depending on the time of day, weekends, and public holidays. Traffic congestion may lead to unexpected delays, especially during peak travel periods.
To minimize risk, it is wise to check real-time traffic updates on the day of departure and allow additional buffer time when planning your journey to the airport.
Booking Notes and Refund Policy
When booking your airport bus ticket, understanding the refund policy is important. A full refund is available if cancellation is made within one hour of booking.
If cancellation occurs between one hour and four hours before departure, a cancellation fee of fifty percent applies. Once the bus has departed, refunds are no longer available.
Even if you purchased a mobile ticket, refunds can only be processed at the departure terminal, so plan accordingly.
Weather-Related Considerations
In cases of severe weather or road closures, airport bus services may be suspended. In such situations, compensation for missed connecting flights is not provided.
To prepare for unexpected disruptions, travelers may want to consider purchasing travel insurance as an additional safety measure.
