This is for anyone who is trying to change/cancel their tickets!!
If you bought your ticket from a travel agent, just go back to the agency and have them change the date. Of course, you'll have to pay the change/cancellation fee due to the ticket regulations and I'm sure that the travel agent should've informed you before you purchase the ticket.
If you bought your ticket online, just call up the airline customer service and ask if changes are allowed. Follow the ticket restrictions and regulations.
Changes and cancellations are always according to your ticket regulations. When you purchase the ticket, make sure that you understand the ticket restriction and regulation.
Higher fare tickets should've more flexibility. Lower/cheap tickets are more restricted. Please keep that in mind!
