Data notes
- Passenger totals for all 8 years are based on Incheon International Airport Corporation's official statistics. Passengers = non-transfer passengers + transfer passengers.
- Transfer passenger counts are directly confirmed by an Incheon International Airport Corporation press release (2026-01-26) only for 2019, 2024, and 2025. The other years (2018, 2020–2023) are estimates supplementing public summary figures, and may be replaced with confirmed values once the original semiannual final-tally CSV is obtained.
- The sharp drop in 2020–2021 reflects the period of restricted international flight operations due to COVID-19.
