This section separates stable airport identifiers from live operating data. Codes, coordinates, timezone, elevation, source identifiers, and accepted reference links are retained here; live arrivals, departures, gates, delays, NOTAMs, and airline schedule changes must still be checked with the airport or carrier.

Entity fingerprint

Field and clock profile
Muan International Airport is a near sea-level field at 35 ft (11 m), positioned at 34.9914° N, 126.3828° E in the Northern subtropics. The runway snapshot lists 1 runway and a longest runway of 9,186 ft / 2,800 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.
City and airport alternatives
Muan is the closest retained city-time anchor at 8.8 km. CJU Jeju City is the closest retained airport alternative at 165 km.
Country airport peers
MWX is compared with CJU Jeju City at 165 km, CJJ Cheongju at 217 km, TAE Daegu at 229 km, PUS Busan at 233 km, ICN Seoul at 276 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.

These operational notes prefer the structured airport facts snapshot, then fall back to the accepted airport reference at muan.airport.co.kr, then blend that with local timezone, route, and city-access data already on this page.
Decision matrix for MWX
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.
When the clock matters
MWX uses Asia/Seoul (KST, UTC+09:00). Use this before overnight arrivals, cross-date departures, and same-day connections.
When surface access matters
Muan International Airport is about 52 km from central Muan (Piseo-ri); build that transfer into arrival and check-in planning.
When alternates matter
CJU Jeju City is the closest retained alternate at 165 km, time difference +0h.
When source checks matter
muan.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.
How this airport compares nearby
These comparisons place MWX inside the retained airport graph by country, timezone, elevation, and coordinate neighbors. They are deterministic dataset facts, not generated flight claims.
Country-rank position
MWX ranks #5 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.
Same-zone airport cohort
MWX shares Asia/Seoul with CJJ Cheongju KR · CJU Jeju City KR · GMP Seoul KR · ICN Seoul KR · PUS Busan KR · TAE Daegu KR. This helps separate same-clock airports by city, country, code, and geography.
Elevation-neighbor cohort
MWX is 35 ft (11 m). Closest elevation peers in the retained airport set include AVV 35 ft (11 m) (0 ft delta) · COV 35 ft (11 m) (0 ft delta) · DIA 35 ft (11 m) (0 ft delta) · HND 35 ft (11 m) (0 ft delta) · CGK 34 ft (10 m) (1 ft delta).
Coordinate-neighbor check
MWX's nearest retained coordinate neighbors are CJU 165 km +0h · CJJ 217 km +0h · TAE 229 km +0h · PUS 233 km +0h.

Airport Details
Timezone
Ground Transport and Nearby Context
Because the airport sits well outside central Muan (Piseo-ri), surface transfer planning matters almost as much as flight timing, especially for late arrivals and early departures.
Gwangju 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.
Muan 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.
Nearby city time anchors
Airport pages are most useful when they bridge into real city clocks. These city anchors are ranked by distance from MWX, then shown with their own timezone, local time, and time difference from the airport clock.
