Modernize your PSS and reservation systems without breaking them.

Hypercubic moves airlines from TPF and COBOL to cloud in quarters — with line-level proofs every PNR, pricing, and inventory path behaves identically, continuously audit-ready documentation of operational and safety systems, and the expertise of your senior engineers captured before they retire.

Solution

TPF and PSS expertise is irreplaceable — and retiring

Reservation, pricing, and inventory systems run on TPF and decades of COBOL using concepts (segment inventory, nested fare classes, interline protocols) nobody teaches anymore. The engineers who understand them are retiring.

HyperTwin

HyperTwin observes how your senior TPF and reservation engineers actually work, then turns each session into a queryable expert model. New engineers learn inventory management, fare filing, and PNR mutation rules from HyperTwin instead of a shrinking pool of senior staff.

Safety and revenue audits require documentation that doesn't exist

Revenue accounting audits, IATA audit cycles, and DOT / FAA inquiries demand traceable documentation of pricing rules, interline settlement logic, and operational system dependencies. Today it's reconstructed under deadline.

HyperDocs

HyperDocs continuously generates audit-ready documentation of every pricing path, interline settlement job, and operational data flow — with traceability to source COBOL and TPF assembler. Audit prep moves from weeks to hours.

A failed reservation modernization could take the airline offline

PSS replatforms have failed catastrophically across the industry. Moving from TPF to cloud without provably identical behavior on every fare, seat inventory, and interline path is a bet nobody takes.

HyperLoop

HyperLoop produces line-level correctness proofs that every PNR operation, fare calculation, and interline settlement path in the modernized code behaves identically to the original TPF and COBOL — so you migrate with evidence, not faith.

Overnight inventory and settlement jobs depend on a shrinking bench

Nightly processing — fare filing, seat inventory rebalancing, revenue accounting closeouts — runs on TPF and z/OS operated by senior engineers with deep JES and SMF expertise. You can't hire more of them.

Measurable Impact

60%

Faster PSS modernization discovery

Airline engineering teams ramp up on TPF and mainframe systems faster, with HyperTwin providing instant access to decades of accumulated expertise.

Faster reservation-systems engineer onboarding

Complete dependency mapping and automated documentation eliminate the blind spots that cause migration failures, schedule overruns, and operational incidents during airline system modernization programs.

90%

Faster revenue and operational audit impact analysis

Airlines reduce the need to extend retiring engineers on costly contracts or engage specialized mainframe consulting firms to reverse-engineer institutional knowledge from legacy codebases.

Common Questions

Can Hypercubic work with TPF-based reservation systems?

Yes. Our platform has deep understanding of TPF, Assembler, and the unique architectural patterns of airline reservation systems. We parse and analyze these specialized environments alongside more common legacy languages.

How do you handle the 24/7 availability requirements of airline systems?

Hypercubic operates as a read-only intelligence layer. We connect to source repositories and operational data without any impact on your production systems. Your operations continue uninterrupted while we build the knowledge layer.

What about proprietary airline industry formats and protocols?

We understand airline-specific data formats including EDIFACT, IATA messaging standards, and proprietary GDS protocols. Our platform is built to handle the unique data structures of the aviation industry.

How does this help with our PSS migration?

PSS migrations are among the most complex IT transformations in any industry. Hypercubic provides a complete understanding of your current system—every fare rule, business process, and integration point—so your migration team can plan with confidence rather than guesswork.

Stop losing the expertise that keeps your airline running

Your senior TPF and mainframe engineers will not be here indefinitely. Hypercubic captures their knowledge so your reservation, revenue, and operations systems remain fully understood after they leave.
