Period of Validity of Ticket

The period of validity is one year from the travel start date (or date of issue if the passenger has not commenced traveling).
Note that the period of validity could be different, however, depending on the applied fare.

The ticket must be used in the order of the itinerary shown on the ticket, starting from the departure location.
If you cannot board flights that make up the itinerary, the ticket will become invalid and you will not be able to board any remaining flights as part of the itinerary.

Please reserve and purchase tickets for flights you will actually board.
If you do not board some of the flights that make up the itinerary, you will not be able to use the ticket as is.
You may have to purchase a new ticket.
Examples: If you reserve and are issued a round-trip ticket for the purpose of only traveling one way, or if you reserve and are issued a ticket for a trip that includes flights that you do not plan to board.
