6. Ways To Reduce Fuel Cost 1%(Total Fuel Cost in 2013)=1%(7,610,000 thousand dollars)=76,100,000 thousand dollars  Fly direct Airspace is still controlled individually by each country. This results in many aircraft flying indirect – adding more than 5% to the total fuel burn.  Flying higher Aircraft engines are much more efficient at low temperatures and atmospheric pressures, which are reached at higher altitudes.
