Accelya Revenue Accounting Processes More Than $120 Billion in Airline Revenue Annually

Macau, IATA World Financial Symposium – October 28, 2026

Trusted by more than 50 airlines, Accelya is modernizing Revenue Accounting through automation and intelligence, providing a controlled financial path for the transition to Order Accounting.

Accelya, a leading global provider of airline software, today announced that its Revenue Accounting solutions process more than $120 billion in airline revenue on an annualized basis.  

The milestone reflects the scale at which airlines rely on Accelya to manage business-critical financial operations and underscores its position in airline finance. It also highlights Accelya’s continued investment in modernizing Revenue Accounting, helping airlines improve efficiency and financial control while preparing for the transition to Order-based retailing.

“Processing more than $120 billion in airline revenue on an annualized basis demonstrates the operational scale and trust behind Accelya Revenue Accounting,” said Sam Gilliland, Chief Executive Officer, Accelya. “We are building on that trust by bringing greater automation, data-driven exception management and decision support, helping airlines improve financial operations today while preparing for Order Accounting.” 

Modernizing Airline Finance at Scale

As airlines expand their networks, distribution channels and ancillary offerings, financial operations are becoming increasingly complex. Greater volumes of transactions, payments, refunds and interline settlements place growing demands on finance teams.

Accelya continues to modernize Revenue Accounting through automation, intelligent support and more efficient exception management, helping airlines handle increasing complexity while maintaining accuracy, visibility and control.

Its solutions support some of the world’s leading airlines, providing the scale and flexibility to manage traditional ticketed transactions alongside newer retailing models. 

Building the Financial Foundation for Order Accounting 

As the industry advances Modern Airline Retailing through Offers and Native Orders, airlines must modernize the financial processes behind retailing without disrupting established accounting, settlement, reporting and control frameworks.

Tickets and Orders will coexist for years, making the transition to Order Accounting a gradual evolution rather than a single technology replacement.

Accelya provides a controlled finance architecture across this transition, building on its established Revenue Accounting capabilities to support the transition towards Order-based retailing.  This approach enables airlines to modernize their financial operations progressively, supporting traditional ticket-based and emerging Order-based accounting models in parallel.

 “Airlines should not have to choose between advancing Modern Airline Retailing and maintaining financial control,” added Gilliland. “Accelya gives airlines a readiness-led path to Order Accounting, preserving business continuity, financial integrity, and simplifying the accounting landscape while supporting the financial operations they rely on today.”
