The most successful airlines are successful because they keep tracking and monitoring their airline operations KPIs.

They’re literally swimming in data and performance indicators.

These airlines understood that every decision has to be based on data and KPIs. If you don’t know your performance at every point in time, you have no idea and no possibility to improve.

That’s why you have to keep a close eye on your KPIs, especially in operations.

Airline Operations KPIs — our most precious knowledge

With this post, we share a part of our most precious knowledge.

Knowledge that has been gathered from KPI projects with airlines around the globe. From large flag carriers to charter and low-cost operator. From network airlines to point-to-point and regional carriers.

Throughout these projects, we defined and set up nearly 100 different airline operations KPIs. Some of the KPIs are common, but some are also very particular.

65 Airline Operations KPIs

For this post, we put together 65 of these KPIs. We have clustered these KPIs according to different operational aspects. 

What’s the idea behind? We wanted to create a source for thoughts for you. A list you can go through to pick up new ideas that will help your airline to become even more successful.
