arrive at Beijing Capital airport on Fri Jul 4 Air Can AC29, then Hong Kong Air China CA115-80 minutes between flights-enough time

Hi,the transfering time is so tight.
The minimum transfering time is around 60 minutes, but the airport is always crowded. So you need to hurry up during the process. Besides, I heard some airline company provide fast transfering service, helping you to transfer as quickly as possible, so you may ask your airline company whether they provide that service.

Hope it helps ~
