If the ticket you purchased was a full-fare first, business, or
economy ticket and is less than one year old, you may contact the
PIA ticket office in the city where you purchased your ticket.
However, if your ticket was a discounted economy fare, it most
likely has restrictions which make the entire ticket
non-refundable. It is essential that you contact the agency where
you purchased the ticket to enquire as to whether it has any value
at all. In most cases it will not.
