Don Mueang is an international airport northeast of central Bangkok, operated by Airports of Thailand. CAAT lists two parallel runways, 03L/21R and 03R/21L, measuring 3,700 m and 3,500 m. The AIP documents instrument procedures, aircraft ground handling and passenger facilities, making the working airport useful for understanding parallel-runway operations and the interaction of airside infrastructure with urban transport. The Royal Thai Air Force aviation museum is nearby. See [CAAT aerodrome information](https://aip.caat.or.th/2026-10-01-AIRAC/html/eAIP/VT-AD-2.VTBD-en-GB.html) for published technical details.
