Country airport index
This page lists 8 retained airport records in our curated South Korea airport catalog with IATA and ICAO codes, city names, and local timezone information. Airport records come from OurAirports and timezone rules come from the IANA database. Click any airport for coordinates, elevation, the current local time, and nearby airports.
Content reviewed Apr 30, 2026. This airport index is reviewed as a curated reference surface. It does not claim complete aviation coverage for South Korea; it lists 8 retained airport records (8 large airports) across Asia/Seoul.
Coverage note. This is an airport-reference index for timezone and travel planning. It focuses on retained large and medium airport records with usable codes and coordinates, not every runway, heliport, closed facility, or local landing strip. Airport service levels, terminal operations, route availability, and codes can change; verify with the airport, airline, NOTAM, or official aviation source before travel.
Country airport evidence
This page is classified as a compact gateway set. The evidence score comes from static source coverage: codes, airport facts, official domains, city-clock handoffs, IANA zones, operational facts, and country dossiers where present.
Retained scope
compact gateway set
South Korea has 8 retained large/medium airport records (8 large, 0 medium) across 1 IANA zone.
Code and entity coverage
8 IATA, 8 ICAO
8 retained records have airport-facts rows; 8 cite official airport domains and 8 carry Wikidata entity links.
Traffic and operation facts
2 passenger rows
2 records quote passenger-volume facts; 16 runway counts are aggregated where quoted; 8 records carry scheduled-service flags.
Timezone pattern
single airport-timezone cluster
The retained airport set resolves to one dominant local-clock pattern, but each airport still stores its own IANA identifier for DST-safe calculations.
Verification boundary
35 source URLs
Visible source hosts include cheongju.airport.co.kr, en.wikipedia.org, wikidata.org, ourairports.com, airport.co.kr, gimpo.airport.co.kr, airport.kr, muan.airport.co.kr. These support identity and static facts, not live routes, terminal assignments, NOTAMs, or airline schedules.
Editorial status
manual dossier attached
Manual dossier sources are attached for country-level aviation context; point-in-time statements still defer to the linked authorities.
Source hosts seen in retained airport facts
Traveler planning patterns
Gimhae International Airport (PUS) is the first retained airport to check for South Korea; then scan the 8 large and 0 medium records for regional alternates.
The retained airport set behaves like a single local-clock cluster, but the airport-specific IANA zone still matters around DST transitions and imported calendar events.
4 airport records link onward to vetted city-time pages, so a code lookup can become a local-clock, daylight, holiday, and meeting-time check.
8 retained records carry a scheduled-service flag, but route availability, airline service, terminals, and disruption notices are not live here.
South Korea has a holiday country page on this site, so use it alongside airport time checks for closures, public-holiday pressure, and ground-service planning.
2 retained airports quote passenger-volume facts. Airports without a quoted figure are not ranked by traffic on this page.

Time-zone span
All retained airport records resolve to one IANA timezone (Asia/Seoul, UTC+09:00 KST no DST). Local-clock math is simpler here than in multi-zone countries, but the airport’s stored IANA identifier is still the authoritative reference for DST transition weekends.
Busiest curated airports
These ranks reflect passenger volumes quoted in the curated airport-facts file; airports without a quoted figure are excluded from this card even if they may be locally busier.
Regional peer comparison
Peers are picked by geographic proximity (same continent) and similarity of retained-record counts. Comparison is structural — it does not audit fleet size, national aviation policy, or passenger traffic.

Time-zone planning
For overnight flights, connections near daylight-saving transitions, and cross-border itineraries, use the airport’s IANA timezone instead of assuming every airport follows the country’s primary zone.
Codes, clocks, and city mapping
IATA coverage
8 codes
Useful for passenger-facing flight searches, tickets, airport boards, and quick route lookup.
ICAO coverage
8 codes
Useful for aviation references, flight tracking, weather briefings, and operational documents.
Airport mix
8 large / 0 medium
Gateway airports are prioritized first, but regional airports remain useful for local clock checks.
DST travel risk
Single-zone
Recheck local airport time around overnight arrivals, daylight-saving weekends, and cross-border connections.
These rows connect retained airport records to city-time pages, so a reader can move from a flight code to the local clock, nearby planning context, and meeting-time checks.
