1. If you can't find the itinerary, you can try to make more calls, or turn off the Wi-Fi connection and use 4G traffic. Usually you can find the data the next day.
2. In addition, if you are a "port number transfer" user, there is a certain time difference between user information synchronization and travel calculation, and usually the travel information calculation will be delayed by 1-2 days.
3. If you still can't find the itinerary, please contact the customer service of your operator in time (Telecom 10000/ Mobile 10086/ Unicom 100 10).
