Someone else used his Ctrip member to book a plane ticket for me. Why will I send a text message to his mobile phone the next time I book a plane ticket with Ctrip number?

Booking air tickets has nothing to do with Ctrip account. The text message will be sent to the other party's mobile phone, because the reserved mobile phone number belongs to the other party, not mine. Whoever fills in the mobile phone number in the current account receives the mobile phone text message.

To order a plane ticket, you need to enter the passenger's information, such as name, mobile phone number, ID number, etc., and then you will create the basic information of the plane ticket, and finally the price display and payment.

Extended data:

Consumers should raise their awareness of prevention, buy air tickets through formal channels, go to regular air ticket sales outlets or call airline booking hotlines, and don't believe in the lies of ordering low-discount air tickets to avoid being deceived.

Booking tickets through the internet usually requires a deposit first, and it is not easy to pay the full amount. When ordering air tickets online, consumers should carefully check the e-tickets and check with the ticketing outlets.

Before payment, you must log on to the e-ticket service website or directly call the civil aviation service hotline, or directly call the airline to inquire about the booking details, flight number and seat number, and then make payment after confirming that the booking information is correct.
