HÀ NỘI — Residents of Hà Nội increasingly yearn for a metro line linking Nội Bài International Airport to reduce the costs and travel times for both locals and tourists. If she took the bus from Nội Bài International Airport, she needed to change twice, and it took almost four hours to reach home. Lê Trung Hiếu, Deputy Director of the city’s Planning and Investment Department, said: “In my view, Metro Line No. “Therefore, the investment and construction of the metro line is seen as a pressing priority for the capital,” he said. This would serve as a primary metro line connection between Nội Bài International Airport with the city's second airport in Ứng Hòa District.
