Both Airlines on Amadeus Nevio

Executive Summary

• A common platform can reduce integration effort, but it does not replace SRSIA governance.
• Published Amadeus material positions Nevio as open, modular, AI-enabled modern retailing for full-service and hybrid carriers.
• This article uses Nevio only as a published platform example and does not assess, recommend or compare vendor capability.
• The design focus should move from basic connectivity to policy: who can sell, service, disrupt and settle which products.

Why This Topic Matters

When both partners are in the same vendor ecosystem, stakeholders may assume interline retailing is solved. That assumption is risky.

Commercial rules, data sharing, customer ownership, finance controls and operational exceptions still need agreement.

The opportunity is that common platform patterns can make the SRSIA operating model more executable and measurable.

Industry Background

Amadeus describes Nevio as a modular, open and AI technology portfolio supporting modern retailing beyond Offer and Order.

Amadeus has also described Retailer-Supplier models as a way to move airline partnerships beyond traditional interline and codeshare constraints.

The practical implication is simple: the customer promise has to be designed across offer, order, servicing, delivery and settlement, not only across shopping screens.

Detailed Explanation

Scenario: Both airlines use the same modern retailing ecosystem, reducing integration friction but not eliminating partnership design.

A shared ecosystem can simplify identity, offer, order, servicing and event patterns. If both airlines use compatible retailing components, the integration can focus less on low-level translation and more on business configuration.

That does not mean the Retailer can automatically sell every Supplier product. Airline B still needs to define availability, product eligibility, fulfilment constraints, payment acceptance, refundability and disruption obligations. Airline A still needs to decide what fits its brand, channel and customer servicing promise.

The SRSIA annex should distinguish technical capability from commercial permission. A product may be technically sellable but commercially excluded from an interline flow. A servicing action may be technically possible but limited to the supplier due to safety, airport or regulatory constraints.

The biggest benefit is observability. Common platform events can make it easier to trace offer creation, order item state, supplier acknowledgement, delivery status and settlement references. This reduces the black-box nature of legacy interline.

The main risk is ecosystem overconfidence. Teams still need exception playbooks for partial outages, partner-specific rules, disrupted journeys, schedule changes and settlement disputes.

Architecture and Operating Model Deep Dive

Offer and product governance

The offer layer is where the commercial promise is created, but it is also where many interline failures are introduced. In Both on Nevio, the offer should not be treated as a screen-level response. It needs supplier provenance, expiry, price guarantee, inventory constraint, product attribute, refundability and settlement intent. The key rule is that every product shown to the traveler must have a known fulfilment path and a known servicing path.

Retailer orchestrates offer; supplier exposes offerable products and constraints That owner should decide which supplier details are displayed directly, which are normalized into the retailer brand, and which are suppressed because the downstream lifecycle cannot support them. The product catalog, offer engine and partner adapter should work together so that the offer is not richer than the operational reality behind it.

Order and record strategy

Retailer order with supplier commitments and shared event model This is the most important system-of-record decision in the scenario. Teams should not simply ask whether an order exists. They should ask which record is authoritative for passenger identity, itinerary, price, entitlement, fulfilment, supplier acknowledgement, payment, refund, exchange and settlement. In hybrid periods, more than one record may exist, but only one should be authoritative for each field.

A good order strategy keeps correlation visible. Offer ID, order ID, supplier order reference, PNR, ticket, EMD, payment reference, settlement reference and disruption event ID should be linked so customer service, airport, operations and finance teams can reconstruct the lifecycle without manual detective work.

Servicing and disruption design

Retailer-led servicing with supplier authorization for affected items This responsibility must be translated into concrete permissions: retrieve order, change itinerary, add item, remove item, refund item, split passenger, reprice supplier product, accept involuntary alternative and close an operational case. If a team cannot say which party may execute each action, the customer experience will depend on manual escalation.

Supplier sends operational event; retailer coordinates journey recovery The supplier owns operational facts such as cancellation, delay, aircraft swap, seat map change or airport delivery failure. The retailer owns the customer journey view. A modern disruption design converts the supplier event into recovery offers, customer choices, order updates, supplier confirmations and settlement adjustments.

Settlement and revenue accounting

Order-linked settlement candidate, with legacy coexistence where required Finance should be involved before launch because settlement fields are not back-office decoration. They determine whether a partner accepts the record, whether revenue can be recognized correctly, whether refunds are allocated to the right party and whether disputes can be resolved from evidence rather than email threads.

The finance-grade order item should carry product owner, seller, supplier, amount, taxes, commission, fulfilment status, refund status, change history and settlement reference. Where a legacy partner remains in the flow, the bridge must map those order item facts to ticket, coupon, EMD or billing records without losing commercial meaning.

Data, observability and audit

Every Amadeus Nevio interline implementation needs an observability model. Teams should trace search request, supplier response, offer construction, customer selection, payment authorization, order creation, supplier confirmation, delivery event, servicing action and settlement event. The audit trail should show what each party knew at the time the customer promise was made.

Operational dashboards should be organized by partner, readiness state, platform, market and relationship type. A spike in order-PNR mismatches, supplier timeouts, failed order changes or settlement rejects should be visible before customers and finance teams discover the issue manually.

Partner onboarding and governance

SRSIA onboarding should be a product process, not only a legal process. Each partner needs a readiness score, supported lifecycle actions, API version inventory, test cases, exception handling model, disruption SLA, settlement evidence checklist and executive escalation path. The output should be a go-live decision that everyone can defend.

The governance model should also define change control. If a supplier adds a new ancillary, changes refund rules, migrates a market to order-native servicing or retires a legacy bridge, the retailer needs advance notice, regression tests and customer messaging updates.

Operational Scenario Walkthrough

1. Search trigger: The customer asks for a journey and the retailer identifies whether the flow is interline, codeshare or virtual interline. At this point the system should already know the readiness state of each partner and which fallback rules are allowed.
2. Supplier content request: The retailer requests supplier content with enough context for the supplier to return a meaningful promise. That context may include route, dates, passengers, loyalty status, channel, currency, point of sale, baggage needs and servicing requirements.
3. Offer assembly: The retailer assembles a customer-facing offer using supplier constraints. The offer should not hide material differences in product, baggage, seat, refund, change or disruption treatment. If a feature cannot be fulfilled or serviced, it should be excluded or marked as conditional.
4. Acceptance and payment: The customer accepts the offer. Payment, fraud, tax, commission and settlement allocations should be captured before the order is confirmed so the financial record can be reconciled later.
5. Order creation: The retailer creates the order or legacy equivalent. The supplier receives a fulfilment request or mirror record. Correlation IDs are written at this stage because retrofitting them after failure is expensive and unreliable.
6. Post-booking servicing: A change, refund or ancillary request is evaluated against both retailer policy and supplier capability. The customer sees a simple servicing action, while the back end may execute order change, ticket exchange, EMD update or supplier authorization.
7. Disruption event: The operating supplier sends an event. The retailer determines whole-journey impact, requests alternatives if necessary, displays customer options and records the accepted recovery path as an order update or legacy servicing action.
8. Settlement close: The retailer and supplier reconcile sale, change, delivery, refund and disruption evidence. Exceptions are routed to a dispute process with enough order and legacy references to avoid manual reconstruction.

SRSIA Annex Blueprint

A strong annex for Both on Nevio should begin with role definitions. Name the Retailer, Supplier, any selling intermediary, any platform provider and any operational delegate. Then define which role owns the customer relationship, which role owns the product promise and which role is allowed to make binding changes after purchase. This avoids the common situation where legal terms are clear but product teams still disagree on who may act.

The second annex area is product eligibility. List the routes, markets, passenger types, fare brands, ancillaries, bundles, loyalty benefits and service attributes that are allowed in the scenario. For each product, state whether it is searchable, sellable, changeable, refundable, disruptable and settleable. If an item is only supported in direct channels or only before ticketing, that limitation should be written into the operating model.

The third area is data exchange. The annex should specify mandatory fields for offer requests, supplier responses, order creation, supplier acknowledgement, servicing actions, disruption events and settlement evidence. It should also define timeout behavior, idempotency rules, duplicate message handling, version compatibility and minimum logging. These details are rarely glamorous, but they are what prevent operational disputes later.

The fourth area is customer treatment. Define what the traveler sees when a supplier product is unavailable, when a price changes, when confirmation is delayed, when a servicing action requires manual handling, or when disruption affects only part of the journey. The retailer should not have to invent customer language in the middle of an incident. The approved treatment should be part of the launch pack.

The fifth area is exception management. Every scenario needs named queues, SLAs, escalation paths and compensation authority. If a supplier cannot confirm, if order creation succeeds but settlement evidence fails, if a refund is accepted by one record and rejected by another, or if the customer is stranded between two partners, the annex should state who opens the case and who closes it.

The final area is change governance. SRSIA is not static. Airlines will migrate markets, retire bridges, add products, upgrade APIs and change servicing rules. The annex should require advance notice, regression testing, release notes, rollback procedures and joint operational readiness sign-off. This turns SRSIA from a launch document into a living operating contract.

Readiness Questions by Function

Implementation Roadmap

The roadmap should be repeated for each partner pair. One partner may be ready for shopping but not servicing. Another may support order events but still depend on legacy settlement. Treat readiness as a matrix by flow, not a binary partner label.

KPI and Control Framework

These metrics should be reviewed jointly by distribution, digital, operations, customer service and finance. SRSIA succeeds when ownership is visible across the lifecycle and failure modes are measured before they become structural cost.
