International Flights: Fare Changes After Reserving and Purchasing
Applicable Fares and Charges
Fares and charges valid for the date of boarding on the date the ticket was purchased will apply. Even if there is a change in the fare amount of the flight after purchasing the ticket, the difference will not be collected or refunded.
- *
If the fare is one where the reservation can be changed and the fare changes due to a change in the boarding date (such as when crossing over normal or peak periods), the difference will be collected or refunded.
Reference Date for Determining Fare
The reference date for determining the fare is the reference date on which the fare for the ticket is determined. The ‘reference date for determining fare’ means the date on which the ticket was purchased, but in some cases, the purchase date of the ticket and the fare application reference date may differ.
The reference date for determining the fare is determined separately for each flight.
Specific Examples
Here are some examples of fare calculation rules and reference dates for determining the fare.
