Identify disrupted PNRs by monitoring the Sabre IROPS queue or subscribing to disruption notifications; retrieve the affected PNR using SabreCommandLLSRQ or the REST PNR retrieve endpoint.
Call the dc-core /pnr/irops endpoint with the PNR locator to obtain the airline's proposed reaccommodation options; options are ranked by the airline's priority rules (frequent flyer status, fare level, SSRs).
Parse the response: each option includes the new flight, new departure and arrival times, availability class, and whether the new routing is ticketable without fare difference.
Apply your corporate travel policy or passenger preference rules to auto-select or present options; for involuntary changes, DOT and EU261 rules may entitle the passenger to a refund if they reject all alternatives.
Confirm the selected option via the IROPS acceptance call, which updates the PNR with the new itinerary and issues a new ticket or exchanges the existing one at no additional charge for truly involuntary changes.
Trigger passenger notification and, if applicable, claim EU261 compensation or DOT automatic refund rights on behalf of the traveller.
Known gotchas
IROPS reaccommodation options are only valid for a limited window; delay in confirming causes the option to expire and the passenger must be re-queued.
Involuntary changes must be distinguished from voluntary changes at the fare-rule level — mis-classifying an airline-initiated cancellation as voluntary can incorrectly trigger a change fee.
For codeshare flights, the operating carrier's IROPS rules govern reaccommodation even if the booking was made on the marketing carrier's ticket stock.
