I land after 22:00. What are my options?
After roughly 22:00 the rail options thin out, so plan the last leg before you fly rather than in the arrivals hall. Check the official late-night bus page and taxi options for your actual arrival day — schedules change and we would rather you confirmed than trusted a page you read weeks earlier. The Incheon Airport to Seoul guide has the comparison and links to the operators' own pages.
