16. Revenue per Employee
One measure to determine an airline’s labor
productivity. It is calculated by dividing an
airline’s total revenue by the number of airline
employee full-time equivalents.

17. Seat Density
Average seating configuration of an airline’s
operating fleet. The measure is derived by
dividing total available seat miles flown by the
number of aircraft miles flown. Aircraft size is
an important determinant of employees
needed to service the operation. Economies of
scale: an airline's CASM declines with
increasing seat density

18. Stage-Length
The average distance flown, measured
in statute miles or Km, per aircraft departure.
The measure is calculated by dividing total
aircraft miles/Km flown by the number of total
aircraft departures performed.
