easyJet Innovates with Databricks and Generative AI in Aviation

EXECUTIVE SUMMARY

easyJet, one of Europe’s leading airlines operating over 300 aircraft across 1,000 routes to revolutionize data accessibility through generative AI and Databricks’ lakehouse architecture. Facing mounting pressure to enhance customer experience and accelerate digital transformation, easyJet needed to empower non-technical staff to extract insights from vast operational datasets. The solution delivered a voice-enabled, AI-driven query tool that reduced time-to-insight by 85%, reached 300+ staff members within weeks, and secured dedicated board funding for expanded AI initiatives—positioning easyJet as a data-driven innovation leader in aviation.

THE CHALLENGE

The aviation industry’s post-pandemic recovery demanded unprecedented agility in customer service and operational efficiency. easyJet, carrying over 69 million passengers annually across 150+ airports in 36 countries, faced critical challenges that threatened its competitive position.

Consumer preferences were shifting rapidly, with passengers expecting personalized, real-time service comparable to leading digital platforms. Traditional data access methods created significant bottlenecks—business users waited days or weeks for analyst-generated reports, missing crucial opportunities for service improvements and operational optimizations. The company’s vast data ecosystem, spanning customer interactions, flight operations, and booking systems, remained largely inaccessible to frontline decision-makers.

Without democratized data access, easyJet risked losing market share to more agile competitors. Customer service teams couldn’t quickly identify trending issues, operations managers lacked real-time insights for route optimization, and marketing teams struggled to personalize offerings at scale. The cost of delayed decisions translated to millions in lost revenue opportunities and decreased customer satisfaction scores. Traditional BI tools proved too complex for widespread adoption, while hiring additional data analysts wasn’t scalable or cost-effective.

THE SOLUTION

Databricks was leveraged as an innovative generative AI solution leveraging Databricks’ lakehouse platform to transform how easyJet’s employees interact with data.

Strategic Approach:
We recognized that true data democratization required eliminating technical barriers entirely. Rather than training hundreds of employees on SQL or complex BI tools, we brought natural language processing to the forefront, enabling users to simply speak their questions and receive instant insights. This approach aligned with easyJet’s broader digital transformation strategy while ensuring rapid adoption across diverse user groups.

Technical Implementation:
The solution architecture centered on Databricks’ lakehouse platform, which unified easyJet’s structured and unstructured data while separating compute from storage for optimal performance and cost efficiency. We implemented:

– Voice-to-Insight Pipeline: Custom web UI with speech recognition capabilities that captured natural language queries from users
– Advanced NLP Processing: Open-source large language models (LLMs) fine-tuned on easyJet’s specific data schemas and aviation terminology
– Intelligent Text-to-SQL Conversion: AI-driven query generation that translated natural language into optimized SQL queries with 94% accuracy
– MLflow Integration: Comprehensive model lifecycle management enabling rapid iteration and A/B testing of different LLM configurations
– GPU-Accelerated Model Serving: Databricks Model Serving infrastructure delivering sub-second response times for complex queries
– Security & Governance Layer: Role-based access controls ensuring users only accessed authorized datasets while maintaining GDPR compliance

Project Execution:
The implementation followed an agile methodology with two-week sprints over a 12-week period:

– Weeks 1-3: Data lakehouse foundation and initial LLM selection
– Weeks 4-6: Voice interface development and text-to-SQL model training
– Weeks 7-9: Integration testing with real user scenarios across departments
– Weeks 10-11: Performance optimization and security hardening
– Week 12: MVP launch and stakeholder demonstration

Our team worked closely with easyJet’s IT, operations, and customer service teams, conducting weekly feedback sessions to ensure the solution met real-world needs. We also implemented comprehensive training programs, creating department-specific use cases that demonstrated immediate value.

THE RESULTS

The generative AI implementation delivered transformative results across multiple dimensions, exceeding initial projections and catalyzing broader organizational change.

Strategic Outcomes:
The platform fundamentally transformed easyJet’s data culture. Customer service representatives now instantly identify trending issues across routes, enabling proactive communication that improved Net Promoter Scores by 8 points. Operations teams optimize flight schedules using real-time demand insights, increasing load factors by 3.2%. Marketing gained the ability to segment and target customers with unprecedented precision, driving a 23% increase in ancillary revenue per passenger.

The successful MVP presentation to easyJet’s board secured dedicated funding for an expanded generative AI roadmap, including AI-driven personal travel assistants and intelligent operational chatbots. This positions easyJet as an innovation leader, attracting top talent and strengthening partnerships with technology providers.
