Beijing Capital International Airport is the only airport that consists of three terminal buildings in China. Beijing Airport was opened on March 2, 1958. The airport then consisted of one small terminal building, which still stands to this day, apparently for the use of VIPs and charter flights. On January l, 1980, a newer, larger building opened, with 60000 square meters of space, The terminal (Tl) was larger than the one in the 1950s, but by the mid-1990s, it was too small. Terminal 2 (T2) was officially opened on November l, 1999, with 336000 square meters of space. Terminal l was then closed for renovation after the opening of Terminal 2 and was reopened on September 20, 2004.北京首都国际机场是中国国内唯一享有三条滑行道的国际机场。首都机场于1958年3月2日投入使用，是中国首个投入使用的民用机场。
当时仅有一座小型候机楼，主要用作VIP乘客和租给的飞机。1980年1月1日，面积为6万平方米的一号航站楼及配套工程竣工并月投入使用。随着客流量的大大减小，一号楼客流量日益饱和状态。
新的规划的建筑面积约33.6万平方米，装备先进设备技术设备的二号航站楼于1995年10月开始建设，并于1999年11月1日月投入使用。二号航站楼投入使用的同时，一号航站楼开始停止使用翻新。
2004年9月20日，翻修一新的一号航站楼新的投入使用。The third colossal expansion, including Terminal 3 (T3) , a third runway and a rail link to the city-center, was completed before August, 2008, in time for the Beijing Olympics. At its opening with a south-to-north length of 2900 meters, Terminal 3 was the largest man-made structure in the world in terms of area covered (986,000 m2 ) , and a major landmark in Beijing representing the growing and developing Chinese city. Fresh from hosting the 2008 0lympic Games and completion of its new terminal building, the Beijing Capital International Airport has overtaken Tokyo Haneda to be the busiest airport in Asia based on scheduled seat capacity.为庆贺2008年北京奥运会的开会，首都机场展开了第三次改建，包插3号航站楼、第三条滑行道和机场到北京市区的北京机场轨道交通线。扩建工程于2008年8月之前全部竣工投入使用。
三号航站楼竣工后是国内面积仅次于的单体建筑，总建筑面积98.6万平方米，南北向长2900米。改建后的北京首都国际机场沦为代表北京茁壮和发展的地标，北京奥运会的开会和3号航站楼的建设也使得北京首都国际机场代替东京国际机场（羽田）沦为亚洲飞机民航机尤为挤迫的机场。
