Although time travel is not conceivable, a timeless experience is. If you don't want to alter your information online, you can do so by calling the customer service centre.

* Contact the airline's customer service centre.

* You will be assigned an executive who will make the necessary changes to your ticket.

* Be specific about the type of adjustment you want to make to your ticket.

* The passengers will then place you on hold as they verify your eligibility according on your fare type and change date. 

* The executive would inform you of the current situation and the associated expenses (If any). The update will be implemented as soon as you approve it and pay for it.
