Project Background

The Client is a flagship European airline. The company is one of the world’s leaders among airlines by fleet size, covered destinations and the total aggregated international flights per year.


The airline was seeking to upgrade its existing online booking portal with new functionality to offer a more diverse and convenient experience to its customers. Another challenge was to set up collaboration with third-party IT vendors delivering other functional parts of the booking platform.



Bearing in mind the plans to increase website traffic, conversion rates and customer loyalty, the Client set the following objectives:

  • Development of a new cross-selling module to offer additional travel products and services, such as hotels, car hire and insurance, up on the booking website.
  • Integration of new travel consolidators to diversify the range of travel products made available for booking online.
  • Refactoring of online payment processing to introduce new payment options.
  • Implementation of dynamic travel packaging based on a new business logic to make the booking more intuitive and easy.


GP Solutions assembled a team of IT experts, which grew from 2 to 16 members over the course of 5 years. The main project development stages are highlighted below:

1. Dynamic Packaging Module

GP Solutions built a custom dynamic travel packaging module allowing the clients to combine and book several travel products within a single booking request.

2. Tour Calendar

A new fully custom packaged tour calendar module was developed. It allows to look up flights within a 3-day window before / after the selected travel dates. This module helps website visitors to make informed choices during ticket booking by comparing the offers for adjacent dates.

3. Connector to American Express

The team developed a new connector to American Express. The main goal of this implementation was to improve the ‘one-time-use credit card’ payment option. After the implementation payments started reaching suppliers directly and allowed to offer better pricing for the end customers and enhance user experience.
