Claim:
A method of modelling a flight of an aircraft using at least one computer system, the method comprising: sourcing flight details from at least one data source using at least one data acquisition system, wherein the flight details are compiled from a plurality of flight detail records within a single flight information region (FIR) and are validated and aggregated via a matching algorithm into a single flight detail record representative of the activity of the aircraft within an FIR; and compiling a single flight model from the validated and aggregated flight details using a processing system, the single flight model indicating the activity of the aircraft over the duration of a journey from a departure port to an arrivals port in: two or more FIRs; or an entire flight undertaken in a single FIR, wherein the processing system uses the flight details to determine utilized services from available services, within an FIR, to the flight; and wherein data representative of the activity of the aircraft in an FIR is not limited to the data recorded in that FIR.
