In late 1999, to mark the 50th anniversary of the founding of the PRC, the airport experienced a new round of expansion as Terminal 2 opened on 1 November of that year. Terminal 1 was then temporarily closed for renovation after the opening of Terminal 2. 20 September 2004 saw the opening of a renovated Terminal 1, which at that time solely handled China Southern Airlines' domestic and international flights from Beijing. Other airlines' domestic and international flights still operated in Terminal 2.
