Lagoon Airstrip (ICAO: AYLQ) is a small, remote airstrip located in Papua New Guinea, serving the local community of Lagoon. It is one of many rural airstrips in the country that provides essential air access to communities otherwise difficult to reach by land or sea. The airstrip supports light aircraft operations and is typical of rural PNG infrastructure, with basic facilities suited to small propeller-driven aircraft. It plays a critical role in connecting isolated communities to regional centers for medical, commercial, and personal travel. No IATA code is assigned to this airstrip, reflecting its status as a local, non-commercial aerodrome primarily used by missionary, charter, and humanitarian flights.
