What should I do if the Xiamen Airlines flight is cancelled? urgent

If the flight is changed due to airline reasons, the airline must assist the guest to change to the next flight or the flight of the same company designated by the guest free of charge. If you book a ticket at the ticket office, ask the ticket office to change it for you. If you book tickets online, you can call the airline directly. You can check the flight to be changed and ask him to change it. It's normal that the phone is difficult to make. Call a few more times and you can get in!
