Data Streaming with Kafka and Flink in the Aviation and Airline Industry

Data streaming with Apache Kafka and Flink is revolutionizing aviation by enabling real-time data processing and integration across complex airline and airport ecosystems. Airlines rely on diverse systems for flight tracking, crew scheduling, baggage handling, and passenger services, all of which generate vast volumes of data.

Kafka’s event-driven architecture ensures seamless communication between these systems, allowing real-time updates and consistent data flows. Flink then processes this data to provide useful information.

IT Modernization, Cloud-native Middleware and Analytics with Apache Kafka at Lufthansa

For instance, Lufthansa leverages Apache Kafka as a cloud-native middleware to modernize its data integration and enable real-time analytics. Through its KUSCO platform, Kafka replaces legacy tools like TIBCO EMS, offering scalable, cost-efficient, and seamless data sharing across systems. Kafka also powers Lufthansa’s advanced analytics use cases, including:

• Anomaly Detection: Real-time alerts using ksqlDB to enhance safety and efficiency.
• Fleet Management: Machine learning models embedded in Kafka pipelines for real-time operational predictions.

This shift enables Lufthansa to decouple systems, accelerate innovation, and reduce costs, positioning the airline to meet the demands of a rapidly evolving industry with greater efficiency and agility.

Business Value of Data Streaming at Amsterdam Airport Schiphol Group)

The business value of data streaming in aviation is immense. Airlines gain operational efficiency by reducing delays and optimizing resource allocation. Real-time insights enhance the passenger experience with timely updates, better baggage handling, and personalized interactions.

Airport modernization and digitalization, with consistent real-time information, is another excellent trend. This includes data sharing with partners, such as GDS systems and airlines. Schiphol Group (Amsterdam Airport) presented various use cases for data streaming with Apache Kafka and Flink.

Scalable platforms like Kafka allow airlines to integrate new technologies, future-proofing their operations in an increasingly competitive industry. By leveraging data streaming, aviation companies are not just keeping pace—they’re redefining what’s possible in airline and airport management.

Virgin Australia: Business Overview and IT Strategy

Founded in 2000, Virgin Australia is a leading airline connecting Australia to key global destinations through domestic and international flights. Known for exceptional service and innovation, the airline serves a diverse range of passengers, from leisure travelers to corporate clients.

Virgin Australia’s IT strategy drives its success, focusing on digital transformation to modernize legacy systems and integrate real-time data solutions. The airline uses the latest technology, such as Apache Kafka, and focuses on efficiency to offer good value and new ideas in the airline industry.

This enables the airline to optimize operations, enhance on-time performance, and quickly adapt to disruptions. A customer-first approach is central, leveraging data insights to personalize every stage of the passenger journey and build lasting loyalty.

Virgin Australia partnered with Confluent and the IT consulting firm 4impact to implement Apache Kafka for event streaming, ensuring their systems could meet the airline’s evolving demands. The following is a summary of 4impact’s published success stories:

• Virgin Australia Flight State Engine (FSE) Replacement
• Virgin Australia Business Flyers (SME) Loyalty Program

Success Story 1: Real-Time Flight Schedule Updates with the Flight State Engine (FSE)

Virgin Australia’s Flight State Engine (FSE) creates a central, authoritative view of flight status and streams real-time updates to multiple internal and external systems. Initially built on Oracle SOA, the legacy FSE faced significant limitations:

• High costs and slow implementation of new features.
• Limited monitoring capabilities.
• Lack of scalability for additional event-streaming use cases.

The Solution

4impact replatformed the FSE with a Kafka-based architecture, introducing:

• Modern Event Streaming: Kafka replaced Oracle SOA, enabling real-time, high-throughput updates.
• Phased Rollout: To minimize disruption, the new FSE ran parallel to the legacy system during implementation.
• Future-Proofing: Patterns, templates, and blueprints were developed for future event-streaming applications.

Key Outcomes

• The new FSE went live in late 2022, delivering zero outages and exceeding performance expectations.
• Speed and cost efficiency for adding new features improved significantly.
• The platform became the foundation for other business units, enabling faster delivery of new services and innovations.

By replacing the legacy FSE with Kafka, Virgin Australia ensured real-time reliability and created a scalable event-streaming platform to support future projects.

Success Story 2: Transforming the Virgin Business Rewards Program

Virgin Business Rewards is a loyalty program designed to engage small and medium-sized enterprises (SMEs). Previously, the program relied on manual workflows and siloed systems, leading to:

• Inefficient processes prone to errors.
• Delayed updates on reward earnings and redemptions.
• High costs due to the lack of automated communication between systems like Salesforce, Amadeus, and iFly.

The Solution

To address these challenges, 4impact implemented Kafka to automate the program’s workflows:

• Event-Driven Architecture: Kafka topics handled asynchronous messaging between systems, avoiding point-to-point integrations.
• Custom Microservices: Developed to transform messages and interact with APIs on target systems.
• Monitoring and Logging: A centralized mechanism captured business events and system logs, ensuring observability.

Key Outcomes

The new reward and loyalty system went live in Q1 2023, processing thousands of messages daily with a minimal load on endpoint systems.

• Reward data was synchronized across all systems, eliminating manual intervention.
• Other business units began exploring Kafka’s potential to leverage data for faster, more cost-effective service enhancements.

With Apache Kafka, Virgin Australia transformed its loyalty program, ensuring real-time updates and creating a scalable platform for future business needs.

IT Modernization with Data Streaming using Apache Kafka: A Blueprint for Innovation in the Airline Industry

Virgin Australia’s success stories illustrate how data streaming with Apache Kafka, implemented with the help of Confluent and 4impact, can address critical challenges in the aviation industry. By replacing legacy systems with modern event-streaming architectures, the airline achieved:

• Real-Time Reliability: Ensuring up-to-date flight information and seamless customer interactions.
• Scalability: Creating platforms that support new features and services without high costs or delays.
• Customer-Centric Solutions: Enhancing loyalty programs and operational efficiency.

The blog post “Customer Loyalty and Rewards Platform with Apache Kafka” explores how enterprises across various industries use Apache Kafka to enhance customer retention and drive revenue growth through real-time data streaming. It presents case studies from companies like Albertsons, Globe Telecom, Virgin Australia, Disney+ Hotstar, and Porsche to show the value of data streaming in improving customer loyalty programs.
