On September 9, Beijing Daxing International Airport held the sixth full scale trial before its inauguration. The trial involved 126 items, 100 aircraft, more than 13 000 passengers, over 9 000 pieces of baggage, 218 check-in counters, 42 carousels, 31 security check lanes, and 287 commercial stores.

In terms of cargo transport, the cargo system in Daxing Airport was tested. Further check was carried out on data sharing and interoperability between relevant information systems of cargo stations, airlines, security check, the customs, and single window, which not only provide one-stop operation and service platform for cargo agents, but also render great support for the development of Daxing Airport Area of China (Hebei) Pilot Free Trade Zone.

For comprehensive transport, further pressure test was conducted on Caoqiao Station, which provides terminal service in the city, so as to check infrastructures, facilities, operational procedures, and service supporting capabilities of Caoqiao Station in a comprehensive manner. The focus of the test was on 8 items, i.e. check-in, baggage check-in, open-baggage security check, and terminal baggage induction system, thus realizing seamless air-rail connection between Airport Express and Daxing Airport.
