Delta Airlines have cutover the Farelogix solution for the calculation of availability for all requests coming from the global distribution systems and airline partners. This is a huge step for Farelogix given the size and scale of Delta Airlines and a massive commercial win. Whilst availability processing is short logical step from the merchandising solution, availability processing is one of the "crown jewels" of airline commercial systems. New technology offers the ability to compute offers in real time on hardware of a modest cost. Amazon, Google and Microsoft have made pay as you go computing a reality offering further cost reductions in the medium to longer-term. Most airlines and their suppliers have had to work very hard and have invested tens of millions of dollars to move shopping away from the more expensive computing environments given the massive increases in volumes of transactions and availability requests from exposure of systems to users, robots and system to modern technology.
