Four central airports that have military components, Tho Xuan in Thanh Hoa Province, Chu Lai in Quang Nam Province, Phu Cat in Binh Dinh Province, and Tuy Hoa in Phu Yen Province, can also involve private investors if the Ministry of Defense transfers runway management to local authorities.

IPP Group wants to invest in Phu Quoc and Tuy Hoa, Vingroup in Chu Lai and FLC in Dong Hoi Airport.
