Air China has received a text message after booking a ticket. Please tell me how to check in at that time and when to arrive at the airport at the latest.

This means that your plane ticket has been confirmed. The specific questions are as follows:

1. The domestic flight arrived at the airport more than an hour earlier because the check-in was stopped half an hour earlier. ) International flights arrive at the airport 2.5 hours in advance and need to go through customs clearance.

2. After arriving at the airport, if there are no checked items, you can print your boarding pass at the Air China self-service check-in counter (not the ticket collection office). If you have checked baggage, you can go directly to the counter of Air China to check in and check your baggage. You can also choose your own seat and check in with your boarding pass.

Three: After boarding the plane (boarding pass), go through the security check (international flights have to go through customs), and then wait at the boarding gate designated on the boarding pass.

4. Flammable and explosive articles, knives and liquid cosmetics with a volume exceeding 100ML are not allowed to be carried, and the water and beverage industries are not allowed to be brought into the security inspection area. Baggage under 5 kg and under 55*40*20 can be carried on the plane, and excess baggage must be checked.
