Passengers traveling through Beijing Capital International Airport exceeded 100 million in 2018, according to the General Administration of Civil Aviation, which is close to its limit.

The administration predicted that passenger numbers through the capital will reach 150 million by 2025.

The new airport-with four runways and a 700,000 square meter terminal-will help to meet the demand and improve the global flight network. It is expected to be the world's largest.

The airport is designed to handle 72 million passengers, 20 million metric tons of cargo and mail, and 620,000 takeoffs and landings annually by 2025. There are long-term plans to expand the passenger number to 100 million annually.
