As the youngest of the four GDS companies, Amadeus has done remarkably well during its short tenure. Yet, in many ways, the company remains an anomaly. Amadeus has the greatest number of travel agency locations with the highest productivity per terminal in the world, yet its booking share is Number 3, and its revenues are dwarfed by Sabre and, to a lesser degree, by Galileo. While the company is Number 1 in locations worldwide, serving the greatest number of countries, it provides the fewest U.S. destinations of the top four GDSs.
