Ctrip's transit ticket has never been issued.

Call Ctrip customer service. Generally speaking, tickets can be issued within 20 minutes. After the payment is successful, you can enter the "My Air Ticket Order" page to check the order status after about 10 to 20 minutes. If the order status shows "Booking Successfully", it means that the ticket has been issued. If the ticket is delayed, you can call Ctrip customer service for consultation, and there will be force majeure factors leading to the cancellation or change of the flight.
