Interline pillar
Interline Offer & Order Architecture
Interline retailing is where modern offers meet the hardest legacy constraints: partner availability, married segment logic, settlement, disruption, servicing responsibility, and mixed order/ticket-native carriers.
Availability
O&D controls and married segments can diverge when partner availability is cached, translated, or repriced in hybrid NDC flows.
Settlement
Orders need clean line-item mapping to tickets, coupons, EMDs, or future settlement records.
Servicing
Changes and refunds require clear ownership when one carrier is order-native and another remains ticket-native.
