Four major Chinese airports have been penalized by Chinese regulators for their poor punctuality records.

The Civil Aviation Administration of China (CAAC) has banned Shanghai Pudong International Airport, Hongqiao International Airport, Urumqi Diwopu International Airport and Tianjin Binhai International Airport from adding frequencies, charter services, and making new route applications.

In a statement, the CAAC added that Pudong and Hongqiao airports continue to be banned from adding frequencies, charter services and making new route applications, after failing to meet the Chinese regulator's performance standards for ten and three consecutive months.

Tianjin Airport remained under a similar ban for failing to meet the required on-time performance standard in November.

Similarly, the aviation watchdog also banned Joy Air from adding new routes and charter services from January 19, while Urumqi airport has been blocked from adding new flights from the same date.

Whereas, the CAAC will release the bans on Nanjing Lukou International Airport from February 1, 2017, allowing it to resume applications for new services and additional frequencies, as on-time performance improved.

The regulator stated that the airline and airports must first meet performance targets for two consecutive months, before further flight applications will be accepted.
