Steps
Retrieve the original PNR and ticket numbers using the Sabre Get Reservation API
POST to /v1/trip/orders/exchangeShoppingCart with the original ticket details and desired new itinerary
Parse the ExchangeShoppingResponse to extract the exchange differential, penalty amounts, and residual value
If residual is positive, display the refund amount; if negative, display the additional collection required
Confirm the exchange by POST to /v1/trip/orders/exchangeConfirm with the selected exchange option
Re-issue the ticket and document the original ticket number in the RTRN field of the new ticket
Known gotchas
Exchange calculations must account for both the fare differential and the change penalty (CAT31); ignoring the penalty field leads to undercharging passengers and agency debt
Sabre ExchangeShopping requires the original fare basis and ticket number to compute the residual correctly; partial information causes an incomplete exchange calculation
Refundable residuals from a voluntary exchange are typically returned to the original form of payment; agents cannot redirect residuals to alternate payment methods without airline authority
