AccelyaAccelya, a global leader in airline technology, announces the launch of FLX ONE, an open and modular retail platform that enables airlines to take full control of their end-to-end OOSD retailing journey. With its cloud-native, API-driven architecture, FLX ONE integrates seamlessly with both existing and future technologies, enabling airlines to transition from legacy systems at their own pace while retaining ownership of their retailing and technology strategy.
FLX ONE is an evolution of the industry-leading FLX platform, built on the same AWS hosted robust, cloud-native technology that powers more than 30 billion offers daily, settles over $100bn annually, and delivers over 50% of global NDC volumes. This allows airlines choosing FLX ONE to immediately adopt and drive value from a live, fully operational platform built for the future with Offers and Orders at its core. FLX ONE integrates the full suite of OOSD capabilities, enabling airlines to create rich and relevant dynamic offers, manage orders in real-time for flexible and accurate bookings, streamline settlement processes for smoother financial transactions, and deliver a seamless passenger experience at the airport.
“We are delighted to announce the launch of FLX ONE, a proven and future-ready platform that gives airlines full control of their retailing” said Sam Gilliland, CEO of Accelya. “FLX ONE is fully open and API-driven, allowing airlines to move away from legacy systems at their own pace, integrate the technologies they choose, and avoid the lock-in of other providers.”

Built on cloud-native technology, FLX ONE allows airlines to integrate seamlessly with their preferred technology providers, free from the constraints of vendor lock-in. Its open, API-driven architecture ensures compatibility with both current systems and future innovations, giving airlines complete flexibility to shape their retailing strategy on their terms. A key enabler of this flexibility is FLX ONE Open Connect, which bridges modern retailing capabilities with legacy Passenger Service Systems (PSS). This integration empowers airlines to upgrade at their own pace, combining the best of new technology with existing infrastructure. FLX ONE Open Connect ensures a smooth, scalable transition for airlines looking to meet the demands of today’s digital-first travellers.
FLX ONE Delivery: Enhancing the Last Mile of Airline Retailing
Accelya announces the launch of FLX ONE Delivery, offering capabilities that streamline critical airport processes and enhance passenger satisfaction by providing a seamless check-in and boarding experience. FLX ONE Delivery enables airlines to manage the entire OOSD journey while unlocking new revenue through personalized, real-time services. FLX ONE delivery will leverage proprietary capabilities from DXC Technology, a leading Fortune 500 global technology services provider, with whom Accelya are delighted to announce a new partnership with. DXC’s capabilities will enable Accelya to build a seamless, FLX ONE Delivery end-to-end experience for passengers, extending retailing to the airport.
“With FLX ONE Delivery, airlines can take full control of the passenger journey, reducing their reliance on legacy systems and ensuring a smooth, end-to-end retailing experience from booking to boarding,” said Sam Gilliland, CEO of Accelya. “This addition makes FLX ONE a fully comprehensive OOSD solution, providing airlines with a proven, ready-to-go alternative to legacy providers, and offering the flexibility and control they need to shape their retailing strategy.”
DXC to become preferred FLX ONE systems integrator
In addition, DXC Technology have been appointed as Accelya’s preferred FLX ONE systems integrator partner. This partnership will enable airlines to efficiently integrate FLX ONE with their existing technologies for faster and more efficient return on investment. Sam Gilliland added, “We’re excited to partner with DXC Technology for their proven expertise, which ensures our FLX ONE platform works seamlessly with airline systems, enabling airlines to modernize quickly and confidently.”
Additionally, Accelya is partnering with SITA, a leading global provider of air transport communications and information technology to integrate FLX ONE Delivery with SITA’s advanced airport systems. This collaboration will enable airlines to enhance their airport operations, delivering a seamless and personalized passenger experience while reducing their reliance on traditional Departure Control Systems (DCS) and streamlining processes such as check-in and boarding.
In a major development that supports the International Air Transport Association‘s (IATA) Offer, Order, Settle Deliver (OOSD) initiative to advance customer centricity with a seamless digital experience, the partnership will focus on integrating Accelya’s commercial systems with SITA’s passenger touchpoints for airport and off-airport passenger processing.
“The rise of digital expectations among passengers, coupled with demand for more personalized travel experiences, shows the need for modern, agile and integrated systems,” said Nathalie Altwegg, Senior Vice President of Airports at SITA. “This partnership with Accelya marks a significant milestone in our commitment to drive the digital transformation of retailing within the aviation industry. By integrating technologies, we can use our deep industry expertise to drive a more efficient and passenger-centric future. We are empowering airlines to deliver a more personalized and seamless travel experience to passengers, setting new standards in how they serve customers and manage their operations.”
Legacy systems such as Passenger Service Systems (PSS) and DCS have long been the backbone of airline operations but are increasingly seen as barriers to innovation due to their complexity and lack of flexibility, as the industry seeks to drive operational efficiencies, enhance passenger personalization and improve security protocols.
Sam Gilliland added: “Accelya is delighted to partner with SITA for our FLX ONE Delivery solution and integrate with their best-in-class airport experience and delivery capabilities. Airlines now have the flexibility, when partnering with Accelya, to seamlessly extend their offer, order, and settle retailing capabilities to the airport through FLX Delivery, which leverages SITA’s technologies and leading airport capabilities. This partnership demonstrates the open nature of the Accelya platform and enables us to bring our comprehensive, yet modular, FLX ONE OOSD solution to airlines, empowering them to control their own journey to modern retailing.”
