3.4 Issue new boarding passes and update ancillary entitlements Passenger Services Agent Amadeus Altéa Departure Control (DCS) Confirmed new itinerary records; pre-paid ancillaries (seat, bag, meal) on original booking New boarding passes issued; ancillaries transferred or refund flag set Boarding pass issuance ≤5 min per passenger post-rebooking confirmation N Y
Phase 4
4.1
Trigger automated SMS and email notifications to affected PAX Passenger Services Supervisor Amadeus Altéa PSS (Notification Engine) Confirmed rebooking records; passenger contact data; disruption reason code Outbound SMS/email sent to all passengers with new itinerary details and self-service rebooking link Notification delivery rate ≥95% within 10 min of rebooking confirmation Y Y
4.2 Update FIDS and gate display boards with disruption status Airport Operations Controller SITA Airport Management System (AMS) Disruption classification, new departure time or cancellation flag, alternate gate assignments FIDS and gate display boards updated; PA announcement script generated for gate agents FIDS update within 3 min of disruption classification confirmation N Y
4.3 Brief gate agents and customer service desk on disruption status Passenger Services Supervisor SITA Airport Management System (AMS) Disruption ops log from AMS; rebooking summary from Altéa Agent briefing completed; customer service desks staffed and equipped with voucher stock Agent briefing completion ≤10 min from IRROP classification N Y
Phase 5
5.1
Assess duty-of-care entitlements by delay duration and cause Passenger Services Supervisor Amadeus Altéa PSS EU261/DOT eligibility flags from Step 2.3; confirmed delay/cancellation duration Duty-of-care entitlement matrix per passenger (meals at 2 hrs, hotel at 4 hrs overnight, transport) Entitlement assessment completed within 15 min of Tier 2/3 classification Y N
5.2 Issue meal and hotel vouchers to entitled passengers Passenger Services Agent Voucher Management System (VMS) Duty-of-care entitlement matrix; passenger count by entitlement tier Meal and hotel vouchers issued; voucher serial numbers logged against PNR for cost recovery Voucher issuance rate ≥90% of entitled passengers within 30 min of threshold trigger N Y
5.3 Manage passenger queue flow at rebooking and check-in desks Passenger Services Supervisor SITA Airport Management System (AMS) Volume of unreboooked passengers at gate; staffing plan from AMS resource module Queue management plan activated; overflow desks opened; escalation to airport authority if required Average passenger wait time at rebooking desk ≤20 min during IRROP event N Y
Phase 6
6.1
Record disruption costs against flight and cost centre in SAP Airport Finance Controller SAP S/4HANA Finance (FI/CO) Voucher serials, interline reissue charges, hotel invoices, overtime staffing costs IRROP cost posting in SAP CO cost centre; accrual for EU261 claims liability IRROP cost posting completed within 24 hrs of event closure N Y
6.2 Submit EU261 / DOT compensation claims data to legal team Passenger Services Supervisor Amadeus Altéa PSS Eligibility flags, delay duration actuals, disruption reason code, passenger PNR list Claims data package exported from Altéa; submitted to Legal and Customer Relations for processing Claims data submitted within 48 hrs of event; EU261 response SLA ≤7 days per regulation N Y
6.3 Generate IRROP performance report and update process KPIs Airport Operations Manager Tableau AMS event log, Altéa rebooking data, voucher costs, customer satisfaction (CSAT) scores IRROP post-event report: rebooking rate, notification rate, avg wait time, duty-of-care compliance, cost-per-disrupted-passenger Report published within 72 hrs; cost-per-disrupted-passenger target ≤$85 (industry benchmark) N N

Airline-Specific Risks & Pain Points

SITA AMS alert feeds from multiple upstream systems (NOC, Jeppesen, Altéa) with inconsistent data latency, causing duplicate or conflicting IRROP triggers during high-volume disruption events
Mechanical IRROPs often escalate from Tier 1 to Tier 3 mid-process due to late MX diagnosis; premature low-tier classification under-triggers rebooking resources
Altéa PSS record locking conflicts when OCC and airport teams access the same flight simultaneously; requires coordinated queue management via PSS administrator role
Passengers booked via third-party OTAs often have incomplete contact data in Altéa, blocking automated notification and requiring manual agent outreach
SSR codes entered by codeshare or interline partners are not always carried over into the operating carrier's Altéa record, creating missed-flag risk for vulnerable passengers
EU261 extraordinary-circumstances defence (e.g. ATC strike, severe weather) requires real-time legal review; automated rules engines in Altéa do not always capture all exemption nuances, exposing the airline to over- or under-payment
