ICN Airport Code: Seoul Airport IATA & ICAO

Incheon International Airport (ICN) is stored for Seoul, South Korea. ICAO RKSI. Timezone Asia/Seoul. This page does not list live flights, fares or terminals.

Overview

ICN is the IATA airport code stored in this dataset for Incheon International Airport in Seoul, South Korea (KR). The matching ICAO identifier is RKSI. Travel agents see ICN on tickets, baggage tags, and GDS segment city pairs (six letters, for example ICNLHR when the other airport is London Heathrow). ICAO RKSI is used in flight plans and ATC, not as the two-or-three-character GDS city-pair token. The IANA timezone recorded for local GDS times at this airport is Asia/Seoul. This code page explains how ICN is used in PNR text. It is not a live departures board. Terminal maps, contact phone numbers, lounge lists, and published flight schedules are not available in this dataset and are not invented here. Nearby airports stored for South Korea: GMP (Seoul). Related IATA city code in this dataset: SEL. To turn a booked PNR that contains ICN into a customer itinerary, paste the cryptic text into the PNR parser.

How to use this page

Confirm the three-letter token on the ticket or PNR is ICN, not a similar code.
Open the PNR parser and paste the full itinerary that contains ICN.
Convert and check that city and timezone match this record.
Use the airport-code page if you only need IATA versus ICAO for ICN.
Do not copy terminal or lounge claims from other websites onto this page. They are not stored here.

Example

Example GDS segment using this airport as origin: 2 AI 101 J 12OCT 1 ICNLHR HK1 0945 1510 12OCT E The parser should read ICN as departure. Times 0945/1510 are local as printed, not converted to your PC clock. If ICN is missing from the dataset, city and timezone enrichment stay empty rather than guessed.
