The recommendation has been sent to the Ministry of Transport for consideration.
Terminal T1 at Noi Bai Interational Airport
The parking lot will cover 1.3 hectares near Terminal T1 to ease the congestion at the current site.
At present, the 17,800-square-metre parking lot can accommodate 555 cars. It often faces jams, particularly at peak travel time.
Early this month, the airport served around 110,000 passengers per day, up 40 percent against the peak of summer in 2019.
Terminal T1 was put into operation in 2001, with an initial design capacity of six million passengers per year. It was upgraded in 2013, increasing the capacity to nine million per year. By July 2017, the airport upgraded the terminal to increase capacity to 15 million passengers per year.
