The air transport market requires high investments, has elevated risks, and low financial return. The competition requires airlines to differentiate themselves by offering better services. On-time Performance (OTP) is an essential service; lack of punctuality affects company costs and revenues. An on-time company generates more satisfaction for travelers, retaining them. Flight delays are identified and reported by airlines through delay codes that are standardized by IATA.

A detailed and specific analysis of an airline's processes was performed to verify the quality of delay code allocation information. It also features the complete mapping of this company's delay code allocation processes and the current quality of the delay code allocation information. In the analysis, comparing the same scenarios for the flights, routes, and departure and arrival times, we found process failures, information divergences, code allocation errors, and differences in the reasons for delays between airlines. This study generated new proposals for improving the current processes of this airline, ensuring data quality and integrity, process improvement. Other airlines can also use this study to identify and improve their delay code allocation processes.
