Regarding the time slot constraint in Beijing, Shanghai, Guangzhou and Chengdu airports, how will Air China ensure relative capacity growth?

At present, the time slots of Beijing Capital Airport, Shanghai Hongqiao Airport and Shanghai Pudong Airport, Guangzhou Baiyun Airport and Chengdu Shuangliu Airport are almost full and quite few chances to add new flights in these airports. Only under the premise of integrating support capability and capacity improvement at these airports can the Company add new flights through bidding, drawing lots and administrative distribution, but we can also increase capacity to a certain extent through the deployment of wide-body aircraft and optimizing route structures.
