Just get your ID number or passport number. You can also check the name and material number on the ticket, but it can only be found through the connecting flight, and it is also difficult to find it. You can find them by entering the check-in system. I used it to check Wilber Pan's flight records. Basically, you can lock whether this person is checking in at the airport, at the boarding gate or at the ticket office ~
He can even know where you bought the ticket at the ticket office, what is the phone number of the ticket office, and what is your mobile phone number and home phone number (in general, it is rare, and the conductor is generally too lazy to lose this kind of thing). Before the flight is delayed and chaotic, you should always check it, because you have to pay a fine for the lost ticket. . .
