Can I change my ticket for free when the plane stops on a typhoon day?

Legal analysis: the plane can be changed for free when it stops in a typhoon. When the flight is cancelled or delayed in a large area due to weather, or the original seat cannot be provided due to other special factors, the carrier, that is, the airline, needs to arrange passengers to transfer or change flights in time, and of course, the change is free. At the same time, when the passenger's cabin changes, the airline adopts the policy of refunding the fare difference more and making up less.

Legal basis: Article 19 of China's Civil Aviation Passenger and Luggage Domestic Transportation Rules stipulates that when a flight is cancelled, advanced, delayed, changed or the original seat cannot be provided, the carrier shall give priority to passengers to take subsequent flights or sign flights with other carriers. Due to the carrier's reasons, when the class of passenger accommodation changes, more passengers will be refunded and less will be made up.
