Please find below the workflow how to process an even exchange in TCP using fare quote for revised itinerary already stored in the PNR.
If the agent starts with Fare Quote anyway and clicks on “USE FOR EXCHANGE BUTTON”, a warning message will appear in the pop-up window about correct procedure for exchange.
So as explained above, it is necessary to start with the ticket, click on (i) and then on EXCHANGE button and use the option “Exchange using store fare quote”.
Once you click EXCHANGE option can be selected
Only now you can click on FARE QUOTE (i) and then on PROCESS button.
Now you can continue as always.
