Airline unit cost index

The below airline unit cost index dashboard presents selected data in action. The index showcases aggregated data of our bottom-up aviation data image. It displays airline unit cost (CASK / CASM) by month, normalized against unit cost values in January 2019. By selecting the 100% seat density option, costs are benchmarked assuming all aircraft were flying with maximum allowed economy seat density (exist seat limit). This feature allows a like-for-like comparison of airline unit cost. The Ex-fuel unit cost option compares all airline unit costs excluding the cost of fuel.
