I booked a plane ticket on Air China's website. What should I do after the ticket is issued?

1, if you book tickets on the website. Displays the ticket issuing status. You can book a seat on the airline website. So you can choose a window seat.

2. After reserving a seat. There is no condition of not printing boarding pass.

3. When you arrive at the airport, you can show your ID card directly at the check-in counter of the corresponding airline for boarding pass and checked baggage.

Besides the computer, you can take a bag. Don't forget: you can't carry air traffic control items with you. Including liquids and cosmetics.
