Is the online ticket of Shenzhen Airlines credible? How to use it? The price will not be higher than what is said on the Internet, will it? I already paid for it. I feel a little hung up. Please give me some advice. Official website's air ticket is credible! The price is generally the same as Taobao's, and it is not compulsory to buy insurance. I will send you a text message after payment, saying that the ticket was successfully grabbed, that is, the reservation was successful. Just take your ID card to the airport for boarding pass and luggage storage on the day of departure. It's convenient. Nothing else is needed. If you don't receive the message of successful booking, call that website to see if the booking is successful. Don't book a flight of Shenzhen Airlines next time, it's often late. . . China Southern Airlines and Air China are the best ~!
