The environmental impacts of civil aviation operations are currently being intensively researched. Aircraft emit various gases during flight, which negatively impact human health and contribute to climate change. Emission values also vary across the different flight phases. Especially on long-haul flights, a significant duration of the journey is spent in the cruise phase. This study examines flight data from wide-body aircraft between Istanbul Airport – Paris Charles de Gaulle Airport and Istanbul Airport – Amsterdam Schiphol Airport. Fuel consumption and emissions were calculated using Automatic Dependent Surveillance-Broadcast data from the aircraft. Python was used to obtain the cruise phase data. The obtained values were comparatively analysed according to aircraft types. In this study, not only fuel consumption and NOX emissions per aircraft, but also fuel consumption and NOX emissions per seat were calculated. In fuel consumption and NOX emissions analyses conducted for both routes, the aircraft with the highest fuel consumption on the Istanbul – Paris flight consumed 60.51% more fuel than the aircraft with the lowest fuel consumption. This value, in comparison, was calculated as 37.97% for fuel consumption per seat. In terms of NOX emissions, the aircraft with the highest fuel consumption produced 10.1% more emissions than the aircraft with the lowest fuel consumption. When analysed per seat, the aircraft with the highest fuel consumption produced 5.36% less NOX emissions than the aircraft with the lowest fuel consumption.
