I just asked my friend to book the plane ticket for me, and the ticket has been issued successfully. Why didn't I get the message?

This may be due to the following reasons:

1, when booking a plane ticket, you filled in someone else's mobile phone number.

2. Due to network problems, SMS will be slightly delayed. Just a moment, please.

Air tickets are registered in real-name registration system. People who book air tickets need to provide the airline or air ticket agency with the passenger's real name, ID number, passport number or Hong Kong, Macao and Taiwan pass number before booking air tickets. Air tickets are divided into discount tickets, transit tickets, e-tickets, return and change tickets, etc.

Extended data:

The airline has set a certain time limit for issuing tickets, and seats that exceed the time limit will be cancelled by the airline. Note that when the time limit for issuing tickets falls on a weekend/holiday, the time limit for issuing tickets must be advanced before the weekend/holiday.

For this time limit, different airlines have their own regulations, such as how many days after booking (for example, 14 days after booking), 14 days before departure, and "on-demand sales" (that is, airlines are required to complete payment and ticketing immediately after booking seats. If tickets are not issued, the airline will not reserve seats.
