Ctrip flight could not be found, but the flight was not cancelled.

First of all, the flight has been cancelled. Due to the difference in time and information between the flight reservation information on OTA platform and the actual flight execution, sometimes the flight is cancelled, the flight is still on sale, or the flight has changed, but the OTA reservation page has not been updated. You can wait a while and search again to see what it is.

Second, the flight seats are full. Usually, if the flight space has been sold, it is normal to find a flight, but this kind of situation is rare, which usually appears in various popular holidays or airline dates with high demand, but it is also very likely to happen.

Of course, in the case of incomplete certainty, calling the airline customer service phone is the fastest way to inquire. Because the airline's official system is definitely more accurate and faster, flight changes can be found in the first time.
