Are there any regulations on how many days in advance flight tickets can be changed? Is there a fee for the ticket change?

There are usually days in advance requirements for ticket changes, which may vary between airlines and different cabin classes. Generally speaking, economy class tickets can be changed 7 days to 14 days in advance, while business class and first class tickets may allow earlier changes, even 30 days or more in advance. For specific regulations, you need to check the official website of the airline where you purchased the ticket or contact customer service.

As for the change fee, under normal circumstances, there will be a certain handling fee for changing the ticket, and the fee standards also vary depending on the airline and cabin class. Some airlines may provide certain discounts or preferential policies on change fees. For specific circumstances, you need to check the terms when purchasing the ticket or consult the airline’s customer service.
