FLY is the front-end of the new Amadeus system for departure control and customer management, customised by BA for the airline with input and testing from customer service staff. The new system has a web-style interface and is supposed to be more user-friendly and intuitive. There are specific flows for certain procedures and in normal circumstances, it's all a case of tapping ENTER and the system guides staff through the flow in a logical sequence, asking for information where required. Everything is colour-coded too and the system, and indeed the Altéa system in general, automates a lot of the work. The idea is that staff spend less time staring their computer screens and more time interacting with the customer, in order to deliver the BA service hallmarks.
