Wattay International Airport history and details

“The airport has a single asphalt-paved runway, which is 3,000m in length.”

The Wattay International Airport, which began operations in 1999, has a single 3,000-long asphalt-paved runway.

The international passenger terminal at the Wattay airport was first renovated in 2005 using the grant aid provided by the Government of Japan.

An airport expansion and upgrade project was initiated by the Ministry of Public Works and Transport of Laos in association with China CAMC Engineering Company in July 2011.

The project included the expansion of the runway by 260m, development of the parking space, renovation of the drainage system, and road upgrades. It also included the expansion of 02 and 03 aprons at the airport for accommodating larger aircraft. New office buildings for the Lao Civil Aviation Department and the LAA were also built.

The total expansion investment was LAK302bn ($37.68m). The Japanese Government provided JPY1.9bn ($23.4m) funding through the Japan International Cooperation Agency (JICA).

Ground was broken for the construction works of the expansion project in December 2011 and it was completed in November 2012. The existing apron was expanded by 78,000m² westwards to accommodate up to ten larger aircraft. A VIP hall was also constructed as part of the expansion project.

The old domestic terminal was expanded with $3m of funding provided by Bouathip Lao Company in February 2012 to ease congestion.
