The ticket has been issued: If you booked a discounted ticket, you can only change the time on the same airline if the change conditions permit; if you booked a full-price ticket, you can endorse and change the time. However, endorsement must be an agreement between the two airlines; tickets with lower discounts may not be able to be changed due to airline restrictions;

In addition, cancellation or modification of unticketed orders will not be allowed. Fees will be charged (except for group tickets for which a deposit has been paid); when a refund or modification is required for an issued order, it must be implemented in accordance with the regulations of each airline, and corresponding refund or modification fees may be charged.
