How do I change my ticket?

If a passenger needs to change the flight, date and class of cabin after purchasing the air ticket, he must propose it two days before the departure of the originally designated flight, and can only change it once. After purchasing tickets, if passengers need to change the flight, date and class of accommodation, they should make a request 48 hours before the scheduled departure time of the originally designated flight. If you change the class of accommodation, you will have to refund more and make up less. Tickets can only be changed once. If they are changed again, they must be re-purchased in accordance with the relevant regulations on refund. However, due to cancellation, advance, delay, flight change or inability to provide original seats, airlines should give priority to passengers on subsequent flights as much as possible, or sign flights with other airlines for them; If the passenger's class needs to be changed due to the above reasons, it will be refunded more and replenished less. There are several types of ticket change: cabin change; Change the flight date; Whether the change of passengers and carriers is voluntary or involuntary is handled in different ways. If the domestic flight ticket is an OK ticket, that is, a signed ticket, it can be changed within one year. If it is an open ticket, that is, a few tickets with unconfirmed seats (non-OK tickets), there is a one-year limit from the date of invoicing to the date of confirmation. After the date is confirmed, that is, after OK, there is still one year to change the time limit. The number of times you can change your ticket is different from that of domestic airlines, but at least once. At present, most airlines have such a rule: as long as seats are available at that time and within the effective time limit, they can change their tickets.
