- The score is calculated based on the basic statistics, and it includes the following 18 variables: Pre-tax profit, Operating revenue, Profit margin, Airline image, Transported pax (since start), Airline age, Credit rating, Fleet size, Fleet utilization, Fleet age, Fleet condition, Fuel burn per passenger, Route ASK, Route RPK, Route LF, Punctuality, Number of weekly flights, Number of airports served. These stats have been chosen since they represent a broad selection of all the possible stats, but leaving out some stats that are duplicates (like pax YTD / pax all-time) or could be easily manipulated in the short term (number of staff for example).

- The calculation method is simple. For each of the stats the maximum number of points achievable is the number of airlines. The airlines in position #1 get this amount of points, and the last airline(s) in that stats category will get 1 point. In case of shared rankings (e.g. 3 airlines in rank #1) the shared ranks receive the same points (e.g. first three max points, and fourth will have points equalling the fourth ranking).

- The system also calculates a maximum achievable score value which is simply all the scores of rank #1 combined factored by *0.95 (to make it a bit smaller).

Note that *out of 18 variables, 9 are not directly affected by size*: Profit margin, Airline image, Airline age, Credit rating, Fleet utilization, Fleet age, Fleet condition, Fuel burn per passenger, Punctuality. But the other 9 are highly correlated with airline size.
