Who knows what the message sent by the mobile phone after booking a plane ticket is?

Did you make a reservation online or by phone?

I usually make reservations online. After I book online and pay through Alipay, the system will send a short message to my mobile phone. The general content is: the ticket for the scheduled flight has been issued, followed by the ticket number, and then remind you to register at the airport two hours in advance that day.

If it's this message, it means that you booked the ticket successfully. Just take your ID card and go to the corresponding airline window at the airport to check in.

Just in case, it is best not to delete the message.
