The terminal building, the second-largest single-building airport terminal after Istanbul Airport, with an area of more than 1,000,000 m2 (11,000,000 sq ft), was completed on June 30, 2019, and the airport is expected to be open on September 30, 2019. Upon completion, it will serve as a major international hub airport in Northern China. There will be 4 runways, and 79 contact aircraft stands.

Upon the opening of the new airport, Beijing Nanyuan Airport (currently solely served by China United Airlines) will be closed.
