How to "return and change" a large-scale flight delay?

What do you mean by "returning and changing the flight"? "Changing the flight" refers to "rescheduling", that is, changing the travel date or other time of the day on the same route where the same airline performs the flight task without changing the itinerary. "Refund", as the name implies, is to ask for a refund because of personal reasons or airline reasons. "Sign" refers to the sign-off between different airlines. Generally, there must be an agreement between the two airlines that sign and transfer. At present, some airports cancel flights due to weather, and airlines can sign flights and call the airport hotline for consultation. Precautions for returning and changing the visa When the flight is cancelled due to the weather or the airline's own reasons, the general airline will inform the passengers that they can return and change the visa. At this time, passengers who need to change their tickets will flock to the airline ticket counter at the airport, waiting for a refund or a change of business. Therefore, for passengers who need to change their visas, don't just "wait" for a seat in front of the sales counter at the airport. At this time, you can log on to the major booking websites through your mobile phone, or simply call the airline's booking phone or call the ticket agent to "grab" a ticket first. Then, go through the refund procedure. Airlines have different regulations on "returning and changing visas" purchased by passengers. Please refer to the regulations of official website Airlines for details. Here are two suggestions for passengers who need to return and change their visas: 1. Change of flight: When the flight is abnormal due to weather, airlines generally provide the following ways to change the flight: (1) Contact the original ticket sales office for handling. (2) Call the airline service hotline. (Generally, agents can reschedule air tickets, and if they pay by credit card, they can reschedule them by hotline) (3) Go to the ticket office directly under any airline. (4) Log in to the airline official website for processing (generally limited to tickets purchased in official website) (5) Queue up at the ticket counter where the airport is located. Passengers are advised to go to the original ticket office to avoid waiting at the airport and hotline. 2. Refund: It must be handled at the original ticket issuing point. You must travel to travel itinerary with your valid ID card and e-ticket. If you pay by bank card, you must also provide the bank card paid at the time of ticket purchase. Some ticket agents also need to provide proof of flight delay. Refund is valid for one year from the date of ticket purchase (unless otherwise stipulated in the special ticket). Generally speaking, passengers can choose to refund or change their tickets for flights cancelled due to the weather and the airline's own reasons. Passengers who need a refund will be fully refunded by the airline.
