Whether it is possible to change your flight date or route, depends on the ticket that you have booked. Every ticket has its own conditions. You can see the conditions of your ticket when you select your flight during reservation.
In many cases, fees apply when making a change in a booking. Sometimes the conditions of the ticket are so strict that changes are not allowed and there is no choice but to purchase a new ticket. For more information about flight changes, go to My Trips.
Please note that when you decide to change your ticket, the validity of your travel documents and any visas may have expired. Please note that additional purchased services such as seats, luggage and / or meals should also be changed.
