Gimpo International Airport is a near sea-level field at 59 ft (18 m), positioned at 37.5583° N, 126.7910° E in the Northern mid-latitudes. The runway snapshot lists 2 runways and a longest runway of 11,811 ft / 3,600 m. The airport clock uses Asia/Seoul (KST, UTC+09:00), so cross-date arrivals should be checked against this zone rather than the airline origin city.
Bucheon-si is the closest retained city-time anchor at 6.6 km. ICN Seoul is the closest retained airport alternative at 32 km.
GMP is compared with ICN Seoul at 32 km, CJJ Cheongju at 113 km, YNY Gonghang-ro at 174 km, TAE Daegu at 249 km, MWX Muan (Piseo-ri) at 288 km inside the retained South Korea airport set, which is useful when backup airports share the same country context but differ by city, route network, and clock behavior.
GMP-CJJ Cheongju: 113 km, about 59m, +0h. GMP-YNY Gonghang-ro: 174 km, about 1h 3m, +0h. GMP-FNJ Pyongyang: 209 km, about 1h 6m, +0h. GMP-TAE Daegu: 249 km, about 1h 9m, +0h. These are distance and timezone references, not live flight availability claims.

OurAirports classifies GMP as a large airport with scheduled service; the airport name and codes identify it as an international gateway for Seoul.
GMP (RKSS) is a near sea-level field at 59 ft (18 m) in the mid-latitudes, kept in the curated set for its route, timezone, and market-planning value.
GMP sits in a broader regional network with 5 nearby curated alternatives, so airline choice and connection strategy are part of the planning story here.
GMP's runway record lists 2 runways, with the longest runway at 11,811 ft / 3,600 m and source surfaces recorded as asphalt (2).
Korea Airports Corporation is the clearest operator or management signal we currently have on file for GMP.
These operational notes prefer the structured airport facts snapshot, then fall back to the accepted airport reference at gimpo.airport.co.kr, then blend that with local timezone, route, and city-access data already on this page.
These are the specific situations where this airport page earns its keep: time-zone conversion, city transfer planning, nearby airport backup logic, and source-confidence checks before acting.
GMP uses Asia/Seoul (KST, UTC+09:00). Use this before overnight arrivals, cross-date departures, and same-day connections.
Gimpo International Airport is about 17 km from central Seoul; build that transfer into arrival and check-in planning.
ICN Seoul is the closest retained alternate at 32 km, time difference +0h.
gimpo.airport.co.kr is listed as the official airport website in the airport facts snapshot; live schedules, gates, routes, terminals, and NOTAM-sensitive operations still need official airport or airline verification.
These comparisons place GMP inside the retained airport graph by country, timezone, elevation, and coordinate neighbors. They are deterministic dataset facts, not generated flight claims.
GMP ranks #3 in the curated South Korea airport set when large airports are listed before medium airports, then sorted by IATA code. The retained country set has 8 airports.
GMP shares Asia/Seoul with CJJ Cheongju KR · CJU Jeju City KR · ICN Seoul KR · MWX Muan (Piseo-ri) KR · PUS Busan KR · TAE Daegu KR. This helps separate same-clock airports by city, country, code, and geography.
GMP is 59 ft (18 m). Closest elevation peers in the retained airport set include NAN 59 ft (18 m) (0 ft delta) · SDQ 59 ft (18 m) (0 ft delta) · XMN 59 ft (18 m) (0 ft delta) · LGB 60 ft (18 m) (1 ft delta) · DXB 62 ft (19 m) (3 ft delta).
GMP's nearest retained coordinate neighbors are ICN 32 km +0h · CJJ 113 km +0h · YNY 174 km +0h · FNJ 209 km +0h.

The airport sits in the normal outer-ring range for a major metro gateway, so rail, shuttle coach, and ride-hail all matter when you judge the fastest arrival.
Seoul is the nearest mapped city anchor in the current dataset, which makes it the cleanest companion page when travelers want to switch from airport timing into local city timing.
Gimpo International Airport has 5 nearby indexed airport alternatives, which makes backup departures and diversion logic part of real planning instead of a theoretical edge case.
Airport pages are most useful when they bridge into real city clocks. These city anchors are ranked by distance from GMP, then shown with their own timezone, local time, and time difference from the airport clock.

Gimpo International Airport does not have a long carrier list in the current source trail, so this page emphasizes the durable pieces travelers can safely use here: local time, field identifiers, nearby airports, and timezone differences.
The route timing references show the first cross-timezone planning burden after this airport: Cheongju (CJJ), Gonghang-ro (YNY), Pyongyang (FNJ). Treat them as distance and clock cues, then verify flight availability with the carrier.
