After successfully entering where to go to official website, choose Chengdu to Shenzhen and the time you want to leave, and click Search. As shown in the figure below.
After entering the verification code, you will see many of the following aircraft routes. Here, you should choose direct flight or transit according to your actual situation, departure time, requirements for airlines, departure time and so on. After choosing your own flight, just click "Book" on the right.
Attention, what I want to say here is that even if you choose the right flight, you should pay attention to whether there is a direct flight sign. Under normal circumstances, if you choose direct flights, you will enjoy more services, but not necessarily.
After successfully entering official website, you will see a person filling in boarding information, etc. If you are already a registered user of Qunar, it is very convenient to fill in. If not, you can fill it out yourself. If you fly frequently, it is very convenient to register an account where to go.
The next page is to confirm the payment, as shown in the figure below. Be sure to check it carefully.
After entering the payment page, because you want to pay by credit card, you need to select "Account Payment", as shown below, and enter your own credit card. After submission, there will be information such as credit card payment password to be filled in. If you pay successfully, you will receive a short message immediately. Note that due to the lag of the network, you may not receive SMS.
At this point, the page will prompt that tickets are being issued. In this way, you successfully booked a plane ticket with your credit card. Note that even if it says that the ticket is being issued, or the ticket is failed, the ticket is successful, etc. You need to call the official customer service immediately to reconfirm the ticket issuance. Sometimes if the ticket fails, it may be because of network problems, and the staff will help you manually issue the ticket after receiving your call.
