TABLE 2-6 Average Fuel Consumption of Typical Jet Aircraft

As observed in Fig. 2-5, the fuel consumption in gallons per
available seat mile decreases with increasing route segment length.
This ratio has become increasingly significant to aircraft operations
as the price of fuel has increased dramatically in the early part of the
twenty-first century. Most significantly for airport planning and
