Cross-Selling Engine for a Leading European Airline

Client Overview
A major European flag carrier, known for its global reach and extensive international route network, partnered with GP Solutions to enhance its digital booking experience. The airline aimed to boost ancillary revenue by introducing a cross-selling module into its existing flight booking engine — making it easier for travelers to book additional services like hotels, car hire, or travel insurance.
Challenge
To stay ahead in a competitive market, the airline needed:
-
A smart and dynamic packaging engine to suggest relevant services based on the user’s flight data and behavior
-
Integration with multiple travel consolidators and service providers (including Pegasus Solutions, Hotelbeds, Avis, and more)
-
Enhanced payment processing logic with expanded options, including one-time-use virtual cards via American Express
-
Close collaboration with a third-party vendor managing the rest of the booking infrastructure — requiring tight coordination and seamless integration
Our Solution
GP Solutions delivered a fully customized cross-selling module designed to complement and extend the existing booking workflow without disrupting the core flight purchase process.
Key Deliverables:
-
A dynamic tour packaging system, operating independently from the core flight engine
-
Preview calendar showing best package options within a +/- 3-day window
-
Advanced connectors to major consolidators and financial services
-
A flexible module architecture that supports personalization, upselling logic, and business-rule-driven product display
Results
- Loyal customer base increased by 40%, the overall sales volume rose up to 25% as compared to previous periods.
- Complex and elaborate dynamic travel packaging logic produced by GP team helped to optimize the overall patterns of user booking behavior and increase productivity of the customer.
- Payment processing mechanisms based on services provided by American Express (so called “one-time-use credit card”) were significantly improved. At this point, all payments from users reach the suppliers instantly, enabling the latter to offer better pricing.
- The online portal in question became more functional, dynamic and user-friendly. It was honored with the prestigious Travolution award in “Best Airline Website” nomination.
