How to buy a plane ticket online?

The process of purchasing airline tickets online is as follows: 1. First, prepare the ID number, bank card number and related documents. 2. You can buy airline tickets directly in official website, including special fares. For example, China International Airlines, China Southern Airlines, China Eastern Airlines, Shenzhen Airlines, Xiamen Airlines, Shanghai Airlines and Shandong Airlines. 3. You can also download the airline's official mobile APP, or other travel mobile apps, as well as small programs in related software. Just enter your departure place and destination, and choose the right flight according to your travel time. After buying a plane ticket, you must arrive at the airport two hours in advance, because you must find the designated airline counter to exchange your boarding pass, and then pass the security check and wait for your flight in the airport lounge.
