Dong Hoi Airport (IATA: VDH, ICAO: VVDH) is an airport located in Loc Ninh commune, 6 km (3.7 mi) north of Đồng Hới city, capital of Quảng Bình Province, in North Central Coast of Vietnam, about 500 km (310 mi) southeast of Hanoi by road.

[8] The site of the airport was formerly an unpaved airstrip built by the French colonists and used from 1930 to 1954 to launch air raids against Viet Minh forces in the Central of Vietnam and Laotian communist forces Pathet Lao in the Central and Southern Laos during the First Indochina War.

The North Vietnamese fighters took off from Khe Gát Airfield near Phong Nha-Kẻ Bàng National Park instead.

[14] The park contains systems of grottoes and caves, of which Vietnamese and British scientists have so far surveyed 20 with a total length of 70 km.

Besides caves and grottoes, Phong Nha has the longest underground rivers, the largest caverns and passageways, the widest and prettiest sand banks, and the most astonishing rock formations in the world.

At the final conference of the National Council for Cultural Heritage held in Vietnam in 2007, scientists attending the meeting highly praised the scientific documentation of Phong Nha-Ke Bang park.

[16] Since Phong Nha-Kẻ Bàng National Park was listed in UNESCO's World Heritage Sites, the number of tourists to this park increased significantly,[17] which required air links between this province with other major cities of Vietnam, namely Hanoi and Ho Chi Minh City.

The Ministry of Transport of Vietnam has approved this proposal to expand this airport in Q4 of 2018 and to launch more international flight routes.

After the completion of the expansion project in 2020, this airport will have one 4E category runway (3600 m x 45 m) along with one parallel taxiway, capable of serving large aircraft like A350, B787, with two separate international and domestic terminals, designed capacity of 10 million passengers per annum.

Expansion plan has been approved by the government of Vietnam to make this airport capable to serve jumbo jets like Boeing 767.
