Air China official website bought a plane ticket. When will it be sent back to the tour?

In fact, there are two ways to do this. I suggest that the most direct way is to call the counter of Air China's local business department. (It can also be printed at the counter of Air China Airport, and some airports also have self-service machines to print). In addition, call Air China customer service 95583 to confirm whether to send it. Urged as soon as possible. (Because you can't print it repeatedly when you travel to travel itinerary, it will be very troublesome if you lose it in the mail. Mailing is not recommended. )
