PROS and IBS Software Challenge Airline IT Giants with Modular Retailing

HOUSTON – November 04, 2026 – For decades, the technological backbone of the commercial aviation industry has been dominated by a handful of monolithic giants. Passenger Service Systems (PSS) provided by legacy vendors have dictated how airlines create, price, and sell their inventory. Today, however, a newly announced strategic alliance is attempting to rewrite the rules of airline IT procurement. PROS, a leader in AI-powered pricing and revenue optimization, has partnered with travel technology provider IBS Software to deliver a combined, interoperable Offer and Order retailing platform.

This collaboration connects the recently launched PROS Kairos Offer Management system with IBS Software’s iRetail Order Management platform. On the surface, it is a technical integration designed to streamline commercial aviation software. But peeling back the layers reveals a highly strategic maneuver aimed squarely at the market’s growing resistance to single-vendor enterprise lock-in. As carriers race to comply with the International Air Transport Association’s (IATA) modern retailing standards, this joint solution presents a compelling, modular alternative to the traditional end-to-end enterprise suite.

Breaking the Monolithic Mold

The airline industry is currently undergoing a massive structural shift toward "Modern Airline Retailing" (MAR). The ultimate goal is to emulate digital natives like Amazon, allowing carriers to offer richer content, dynamic pricing, and highly personalized traveler experiences. Yet, the road to this retail utopia is blocked by aging infrastructure. Historically, airlines have relied on comprehensive, integrated systems from mega-vendors like Amadeus and Sabre. While these systems provided stability, they also created deep vendor dependency, stifling commercial agility.

"For years, carriers have been held hostage by the sheer gravity of their legacy reservation systems," noted one prominent aviation technology analyst. "If you wanted to change how you sold a seat or a baggage allowance, you had to wait for your PSS provider to update the entire ecosystem."

The PROS and IBS Software alliance directly attacks this paradigm by championing a "best-of-breed" approach. Rather than forcing airlines to buy an entire suite from one provider, the partnership offers pre-engineered integration between two specialized, top-tier systems. This modularity is designed to rival the seamlessness of monolithic platforms without the associated lock-in.

"Airlines have been asked to choose between a single stack they cannot shape and a modular approach they have to assemble themselves," said Somit Goyal, Chief Executive Officer at IBS Software. "Our partnership with PROS is designed to change that equation. By bringing together two companies with a shared commitment to customer choice and innovation, we are creating a more open and practical path to modern retailing; one that preserves flexibility, accelerates transformation, and delivers stronger commercial outcomes."

The timing of this alternative is critical. Competitors are aggressively rolling out their own modern retailing suites. Amadeus, for instance, has seen recent success with its Nevio platform, successfully taking major carriers like Finnair and Saudia live with modern order capabilities in 2025. Meanwhile, Accelya’s FLX ONE platform claims to power nearly half of global New Distribution Capability (NDC) transactions. To compete against these massive footprints, independent vendors must prove that their combined, interoperable solutions can function just as smoothly as a single-vendor stack.

The Pragmatic Path to ONE Order

At the heart of this technological arms race is IATA’s ONE Order initiative. This industry mandate aims to eliminate decades-old fragmented records—such as Passenger Name Records (PNRs), e-tickets, and Electronic Miscellaneous Documents (EMDs)—replacing them with a single, unified customer order.

While the concept is elegant, the execution is terrifying for airline executives. Transitioning to ONE Order requires a massive overhaul of internal processes, revenue accounting, and delivery systems. Furthermore, recent high-profile operational meltdowns across major North American carriers have highlighted the catastrophic risks of IT failures. Consequently, airlines are incredibly hesitant to undertake full "rip-and-replace" migrations of their core commercial systems.

This fear of operational disruption is exactly what the new partnership seeks to alleviate. By offering a modular architecture, the joint platform supports gradual adoption. Airlines can implement the new offer and order capabilities in parallel with their existing legacy PSS infrastructure. This coexistence model allows carriers to incrementally migrate functions over several years, drastically reducing the risk of revenue disruption.

"Airlines want the freedom to modernize on their own terms while improving commercial performance," explained Sunil John, Chief Executive Officer at PROS. "Our partnership with IBS Software brings together best-in-class Offer and Order capabilities in an open, interoperable ecosystem, helping airlines accelerate modern retailing, create more relevant traveler offers, and capture greater value across the retailing lifecycle."

By focusing on a phased modernization approach, the alliance taps into the financial realities of the current aviation market. Airline IT spending has faced recent downward pressure, making massive, upfront capital expenditures difficult to justify. A modular solution that leverages existing investments while delivering faster return on investment (ROI) through improved dynamic pricing is an attractive proposition for cost-conscious Chief Information Officers.

The Agentic AI Advantage

Beyond the structural advantages of modularity, the technical underpinnings of this partnership reflect the cutting edge of travel technology. Both platforms bring significant artificial intelligence capabilities to the table, moving beyond basic automation into the realm of "agentic AI."

Introduced in October 2026, PROS Kairos operates on a unified data architecture powered by Databricks. Its defining feature is an open architecture that utilizes a "PROS Agent Orchestrator." This system coordinates specialized AI agents via open-source Model Context Protocol (MCP) connections, minimizing manual steps in airline commerce and allowing for highly sophisticated, natural language interactions.

Complementing this is the iRetail platform, launched a year prior in collaboration with AWS. Built as an AI-first, cloud-native retailing hub, iRetail manages complex airline orders and functions as a single source of truth across the Offer-Order-Settle-Deliver (OOSD) value chain. Its robust connectivity gateway allows it to function as an independent NDC enablement layer.

The promise of "pre-engineered integration" between these two advanced systems is crucial. In the past, airlines attempting a best-of-breed strategy were forced to act as system integrators, spending millions on custom API development to make disparate software communicate. By pre-wiring the connection between Kairos and iRetail, the two tech firms are promising the flexibility of modularity without the integration friction that has historically plagued independent software deployments.

High Stakes and Industry Implications

The success of this partnership will serve as a bellwether for the future of airline IT procurement. If the pre-engineered integration proves seamless in live commercial environments, it will validate the modular approach, potentially triggering a broader exodus from legacy PSS monopolies.

However, the challenge remains formidable. Legacy providers have deeply entrenched relationships with global carriers and are investing heavily to ensure their own next-generation order management systems retain their dominant market share. Furthermore, while 37 percent of carriers report having active AI programs, only a small fraction have successfully deployed the kind of complex agentic AI that underpins these new platforms.

Ultimately, the transition to modern airline retailing is not merely a technology upgrade; it is a fundamental business transformation. Airlines are realizing that separating retail decision-making from legacy reservation constraints is essential for long-term commercial agility. As the industry navigates this high-stakes migration, alliances that can successfully bridge the gap between legacy reliability and modern digital flexibility will shape the financial trajectory of commercial aviation for the next decade.
