# Select a ticket for exchange

Once you open a PNR:

![](/files/-M858rCoi-eA7iRXmEW0)

You have to select which ticket you will make the exchange for. TCP Exchanges & Refunds service displays all ticktes that are attached to the PNR. Tickets are marked in colours represented by Coupon status (OPEN, VOID, EXCH, RFND, etc.):

![Example with VOID and OPEN status ticket](/files/-M858zLxKFk4QIAGPHPI)
