AIRLINES SPENT MORE than US$200 billion on jet fuel
in 2013, representing more than 30% of their total costs, to
compare with “only” US$46 billion in 2000 (14% of their total
costs). Airline fuel expenses have almost multiplied five
times in 10 years.
As a result, airlines have striven to improve jet fuel efficiency, as
unlike other modes of transport, they had no alternative source
of energy available. Airlines have saved fuel in many different
ways, including reducing and more accurately measuring
on board weight, cruising at higher altitudes, making greater
use of flight-management systems and conducting more
in-depth analyses of weather conditions. In addition, airlines
are modernising their fleets with more fuel-efficient airplanes,
purchasing larger modules together with “densifying” their cabin
layouts, enhancing their operations by increasing load factors
and utilisation, redesigning hubs and schedules to alleviate
congestion and pooling resources to purchase fuel in bulk
through alliances with other carriers.
