Airline Financial Settlement in the Era of Order Accounting
The airline industry is undergoing one of its most significant transformations in decades: the shift from legacy, ticket/EMD-based processes to Offer and Order–based retailing. This evolution does not only redefine how airlines sell and service products, but also how they account for, settle, and recognise revenue. Financial settlement which has for a long time being anchored in structured, sometimes even paper-ticket-driven workflows must now adapt to a world where products are very dynamically created, aggregated, and fulfilled and some standard processes shall vanish. Order Accounting emerges as the essential backbone enabling this transition, promising more flexible, accurate, and real-time financial visibility. Yet the journey will differ considerably across full-service carriers (FSC), airlines in a hybrid operational model, and low-cost carriers (LCC). In this blog I will explore where the industry currently stands, how solution providers are preparing, and what the shift means for each airline type.
Where Is the Industry? Where Are the Providers?
Order Accounting has moved from conceptual discussions to early-stage implementation. Several pioneering airlines, mostly major network carriers have begun foundational work to align their financial systems with the transition to Offers and Orders. However, the industry as a whole is still very much in a hybrid world: tickets and orders (when applicable) coexist, legacy settlement rules and cycles remain deeply embedded, and standards for Order Accounting are still evolving.
Industry status today:
- Standards bodies like IATA have advanced definitions for Orders but are still maturing the accompanying financial processes.
- Airlines are experimenting through pilots, proofs of concept, and phased transformations, primarily focusing on front-end retailing capabilities.
- Technology readiness is uneven—Order Management Systems (OMS) are progressing rapidly, but Order Accounting systems lag behind, often still tied to ticket-based data architecture they are somehow obliged to cope with.
- Interline, IROPs and alliance complexities remain largely unsolved in the context of orders, requiring major rethinking of settlement and clearing processes.
Where providers stand:
The provider landscape is fragmented and still emerging.
- Large PSS and revenue accounting vendors are planning or extending existing systems with “Order Accounting modules,” though the depth of true order-centric design varies significantly.
- New-generation OMS providers are beginning to integrate financial capabilities, but often lack the maturity of established accounting engines.
- Specialised startups are entering the space with cloud-native, modular accounting solutions—innovative, but not yet proven at scale.
- Industry intermediaries (e.g., ATPCO, ARC, clearing houses) are exploring how they might support financial processes in an order-driven world from different anckles.
In short, while the retailing landscape accelerates, the accounting and settlement layer is still forming. This lag poses risks but also creates a unique opportunity for carriers and providers to influence how Order Accounting will work.
Impact of Order Accounting Across Different Airline Types
Full-Service Carriers
Network carriers stand to gain the most from Order Accounting but also face the highest complexity. Their operations rely heavily on interline partnerships, codeshares, prorates, and intricate revenue streams. Under today’s ticket-based system, financial reporting is often delayed, fragmented, and filled with exceptions.
Impact on FSCs:
- Significant back-office simplification as ticket/EMD-based events, coupons, and documents are replaced with a single Order as the source of truth.
- Greater real-time revenue visibility, enabling more accurate profitability analysis across itineraries and channels.
- Improved servicing capabilities, especially for complex journeys involving multiple partners.
- Challenges around interoperability, particularly ensuring cross-industry settlement can function without tickets.
- Major transformation effort, requiring coordination between revenue accounting, finance, distribution, and IT.
For FSCs, Order Accounting is not optional, it is foundational to achieving the full benefits of modern retailing and operational efficiency. But they must plan for a multi-year journey.
Hybrid Airlines
Hybrid carriers operate with a mix of simplicity and complexity, offering ancillary-rich products but occasionally implementing partnerships or network-like structures. They are often more agile and less constrained by decades-old accounting infrastructure.
Impact on hybrid airlines:
- Meaningful efficiency gains from consolidating accounting events into a unified order structure.
- Greater flexibility in pricing and bundling strategies as accounting becomes less tied to rigid ticketing data.
- Reduced settlement overhead, especially for carriers with limited interline exposure.
- Moderate transformation cost, usually lower than for FSCs but higher than for pure LCCs.
- Opportunities for competitive differentiation, as real-time financial data can support more dynamic commercial decision-making.
For hybrids, Order Accounting is both achievable and strategically beneficial. They can move faster and gain advantage by adopting modern retailing earlier than competitors.
Low-Cost Carriers
LCCs often operate with simple, direct-sales-driven models and minimal interline activity. Many already use accounting systems that are relatively modern compared with legacy FSC systems, and they benefit from strong alignment between inventory, sales, and settlement.
Impact on LCCs:
- Lower urgency for immediate transformation existing LCC processes already resemble simplified order structures.
- Simplification benefits still exist, especially around ancillaries, servicing, and financial reconciliation.
- Incremental gains in financial transparency and automation.
- Potential future requirement, as industry ecosystems (including partners, payment providers, and regulators) move toward orders.
- Opportunity for low-friction adoption, thanks to simpler operational and business models.
LCCs will feel the pressure later than FSCs or hybrids, but early awareness and gradual preparation will avoid future disruption.
Wrap-Up
Order Accounting represents the financial foundation of the future retailing landscape. The transformation will be significant but also uneven.
- FSCs must begin laying the groundwork now, as their complexity and interline reliance demand early investment.
- Hybrid carriers have an opportunity to move boldly and gain competitive advantage through modernised accounting capabilities.
- LCCs face less pressure in the short term but should recognise that Order Accounting will become industry-standard and start preparing accordingly.
The provider ecosystem is evolving, but not yet mature. This gives airlines a rare chance to help shape the solutions that will serve them in the coming decade. Ultimately, Order Accounting is not merely a technical upgrade, it is the key to unlocking true airline retailing, efficient settlement, and real-time financial clarity. Those who prepare early will be best positioned to succeed in the new landscape.
