Software Testing for Airlines

Airlines are modernizing systems that have to run stably around the clock - and at the same time are in the midst of far-reaching technological, regulatory and structural changes. Software errors don't just affect operations. They affect passengers, crews, partners and the bottom line.

Since 2007, we have been helping airlines and their IT service providers to manage software quality in this environment in a targeted manner, identify risks at an early stage and reliably safeguard projects along the entire airline value chain. As a full-range provider in software testing, we offer the complete spectrum from test strategy to scalable test factory, from automation to consulting and training.

Industry understanding

Booking systems, loyalty programs, MRO platforms, EFBs for pilots, HR and finance applications, airport and authority interfaces - we know the business processes behind your airline software. This knowledge is the foundation of every testing activity we undertake.

Mastering complexity & dependencies

Airline system landscapes are highly interconnected. Changes at one point have a chain-like effect on other systems - whether legacy architecture, GDS interface or new retailing model. We create transparency about dependencies and consistently align quality assurance with the critically relevant processes.

Seamlessly integrated

We work with the tools that are already used in your environment: Jira/Xray, Azure DevOps, Tosca, Selenium, Playwright, Postman and more. We integrate test management and automation seamlessly into your development and release processes and provide targeted skills so that your teams become independent in quality assurance.

Using AI where it creates real added value

We use AI in a targeted manner: in the analysis of complex requirements, the prioritization of tests, the automation of workflows that are difficult to scale or the acceleration of test processes in hybrid system landscapes. We take data protection, compliance and governance into account right from the start.

Airline Aircraft Puzzle

Software testing with airline experts

Since 2007, we have been helping airlines and their IT service providers to implement software projects securely, sustainably and efficiently.

We are consistently on the side of the software users: the airlines who want to purchase, customize, integrate and accept systems. Our experts bring together specialist processes, technical dependencies and regulatory requirements - in close cooperation with IT departments, but also with specialist departments such as HR, Finance, Operations and the crews.

Depending on requirements, we offer selective support for individual projects or the reliability and scalability of a long-term test factory partner - managed from Germany, with capacities in Rwanda and India.

Quality assurance where,
where airline IT is business-critical

"Testing airline software today means much more than structured test management and automation.

It means keeping an eye on complex business processes, technological changes and high operational stability requirements at the same time - across system boundaries, specialist areas and release cycles.

This is exactly what we do: with almost two decades of project experience in airline IT and a pragmatic, results-oriented approach."

-- Vittorio Monteiro, Managing Director, Head of Service Delivery Aviation

The challenges
in airline IT

Airlines are transforming their IT landscapes: from GDS migrations and NDC retailing to complex system integrations.

The requirements for stability, compliance and customer experience leave no room for error. The answer to this is never generic: it follows the system landscape, the operating context and the requirements of the respective project.

We have been familiar with these challenges and many more from our project experience since 2007.

Hybrid system landscapes and airline retailing
Most airlines today find themselves in a structural dilemma: legacy booking architectures and new, order-based retailing models based on NDC and ONE Order run in parallel - and often have to do so for years to come.

Changes in one system must remain compatible with the other. Errors at system boundaries jeopardize sales, customer experience and operational stability in equal measure. Holistic, cross-system quality assurance is not an option, but a prerequisite.
GDS complexity and integration risks
Global distribution systems such as Amadeus, Sabre and Travelport form the backbone of many airline IT architectures. Changes to booking logic, offer creation, interlining or settlement processes have an impact on numerous downstream systems - with proprietary interfaces, specific test requirements and tight release cycles.

Without in-depth GDS know-how on the part of the testers, blind spots arise here with serious operational consequences.
Time-to-market with increasing system complexity
Test data governance and data protection
Realistic test data is particularly critical in airline IT and at the same time particularly difficult to obtain: Passenger name records, payment data and personal passenger information must be data protection-compliant, technically consistent and available in sufficient quantities. Manual data creation is error-prone, time-consuming and does not scale. Automated solutions create the necessary scope here.

Experience from many years of airline transformation

"Since 2007, I have seen the airline industry go through numerous transformations.

Technologies, architectures and business models change, but one thing remains constant:

Critical airline systems must be stable, integrated and reliable.

Software quality is therefore not a downstream test step, but a central prerequisite for successful transformation."

-- Christian Knoop, Founder & CEO

Test data and test environment management for airline systems

Realistic test data and stable test environments are the foundation of resilient quality assurance - and both are particularly complex to organize in airline IT.

We take on this task operationally: with experienced specialists who know your test landscape, coordinate environments aligned with the release schedule and ensure that data and environments are consistent, close to production and available for parallel teams.

For test data specifically, we bring our own tooling: Our Test Data Hub automates the creation and management of mass test data for GDS systems, legacy interfaces and hold systems such as Amadeus, Sabre and Travelport - including PNRs, special service requests and complex operational situations, compliant with data protection regulations and available in minutes.

What it brings you:

Test data for all phases without manual effort
Stable, production-aligned test environments in sync with your release schedule
Consistency across system boundaries and environments
Accelerated release cycles through automated deployment

Performance and load tests for mission-critical systems

Booking systems, check-in processes, payment gateways and passenger portals must react quickly and stably under peak load - during sales launches, IRROPS or system migrations. A timeout at the wrong time is not a technical detail, but a sales and customer problem.

We test your critical systems under realistic load scenarios, identify bottlenecks in applications, interfaces and infrastructure and make weak points visible before they occur in productive operation.

What it brings you:

Stable performance even in extreme scenarios
Early visibility of capacity risks and bottlenecks
Reliable basis for go-live decisions

More about load and performance tests

End-to-end testing across system boundaries

The greatest quality risks do not arise within individual systems - but between them. We validate the handover points between legacy architectures and modern order management systems, check process integrity along the entire order lifecycle and comprehensively safeguard scenarios such as dynamic pricing, interlining and order-to-cash.

More about E2E-UATs

With us, you can ensure that both system worlds - the existing and the new - work together reliably without any quality or sales risks arising at the interfaces.

How it benefits you:

Seamless protection of critical transfer points
Early detection of data consistency and integration errors
Greater security when introducing new retailing architectures
UAT support: from scenario design over test execution to sign-off recommendations

Airline Retailing Transformation

Airline retailing is fundamentally changing the system landscape of airlines. Traditional legacy structures with PNRs, ticketing and batch-driven processes meet modern retailing components such as offers, orders, dynamic pricing and event-driven architectures.

Both worlds often have to function in parallel over a long period of time - with complex dependencies between existing and new systems.

This is precisely where key quality risks arise: Data consistency, process integrity, interface stability and financial processes such as settlement and billing must be reliably safeguarded.

We support airline retailing transformations with end-to-end tests, integration checks and targeted validation of critical business processes - so that innovation does not come at the expense of stability, revenue security or customer experience.

What it brings you:

Coexistence of legacy and retailing systems
Early detection of integration and data consistency risks
Greater security for NDC, ONE order and order-to-cash transformations

QA consulting, test strategy and maturity analysis

Not every airline starts with the same QA structures - and that's not a problem. We support you in soberly assessing the status quo of your quality assurance, identifying gaps and developing a test strategy that fits your system landscape, your teams and your goals. Methodologically sound, practical and without any conflict of interest.

If you wish, we can also provide operational support during implementation.

What it brings you:

Clear view of your QA maturity level and specific need for action
Tailor-made test strategy for your environment
Independent external assessment

Quality assurance,
that works in everyday project work

"In airline projects, quality is not only evident in the test report, but in the ongoing interaction between people, processes and systems.

Our aim is to noticeably relieve teams, make risks visible at an early stage and organize quality assurance in such a way that it works in everyday project life - pragmatically, transparently and close to the technical realities of the airline."
