ONE Record: From Standard to Strategic Advantage in Air Cargo
ONE Record is redefining air cargo data sharing, enabling airlines to move from legacy systems to a more connected and efficient ecosystem.
Give customers and partners fast, consistent availability that you control – built to support modern airline retailing without relying on the PSS for every request.
Airlines need availability they can trust: fast for shoppers, consistent across every channel, and flexible enough to support modern airline retailing. FLX ONE Availability Calculator delivers this by generating availability without relying on the PSS for every request.
It uses live schedules, updated cabin counts, and inputs from Revenue Management to produce accurate, up-to-date results in real time. You stay in control of how availability works, improve performance, and reduce PSS-related costs, while easing pressure on legacy systems and keeping results consistent.
Travelers and partners see fast, consistent results. With availability calculated directly in FLX ONE Availability Calculator, response times improve across all channels and retailing becomes more reliable, without increasing PSS traffic.
When availability doesn’t depend on constant PSS calls, the pressure on older systems drops. Airlines avoid unnecessary scan charges, cut down on system load during busy periods, and reduce the risk of slowdowns or interruptions when demand spikes.
Every airline has different priorities. With FLX ONE Availability, rules can be adjusted to reflect demand, seasonality, route focus, or revenue insights. Teams can fine-tune how availability behaves without long system changes, allowing decisions to translate into action more quickly.
Modern retailing needs availability that keeps up with real-time shopping and pricing. By calculating availability in the platform, airlines get dependable results that work smoothly with NDC, dynamic pricing, and new digital retailing flows – making it easier to bring new retailing ideas to market.

FLX ONE Availability Calculator is a real-time engine that calculates seat and class availability directly inside the FLX ONE platform. It uses live schedules, cabin updates, and inputs from Revenue Management to produce fast, consistent availability across all channels, without relying on the PSS for every request.
The engine combines three key data sources: schedules from FLX ONE Schedule Builder, updated cabin counts from the airline, and inputs from Revenue Management such as bid price or other commercial guidance. It uses these to calculate availability in real time, providing accurate results without sending frequent requests back to the PSS.
Calculating availability off-PSS reduces load on legacy systems, avoids unnecessary scan charges, and improves response times. It also helps airlines prevent channel mismatches and ensures customers and partners receive consistent results.
Cached availability can become outdated and create inconsistencies between channels. FLX ONE Availability Calculator processes each request in real time, giving customers and partners up-to-date availability every time.
Modern retailing relies on real-time data and consistent results. By calculating availability inside the platform, the product supports faster request volumes, richer shopping flows, and dynamic pricing models used in NDC and digital channels.
