We can't find the WeChat ticket after it was changed.

After manually contacting the customer service to change the ticket, the ticket information on WeChat did not change, probably because the staff who changed the ticket did not transmit the changed record information to the information change recorder in time. So the information records were not uploaded to the personal information system in time. At this time, you can only query the real-time information of the plane in time, so as not to affect your trip and delay your work.

There are two kinds of ticket change and train ticket change. Ticket change includes change (change of the same level and upgrade) and signing (change of the airline). The change of train ticket refers to the visa procedures for early or late travel when the number of trains and trains changes after the purchase of train tickets.
