Air Canada has created a series of steps to save on fuel, including reducing cruising speed when flights are ahead of schedule and when an aircraft has prevailing winds.
WestJet Airlines has also been creative, using computer technology to calculate optimum speeds so slowing down doesn’t extend the work shift and add to staffing costs.
WestJet also uses an onboard GPS system to allow planes to come in for more direct landings via satellite, cutting travel time and fuel expenses. Other airlines are following Canadian airlines.
Southwest Airlines, which started flying slower two months ago, projects saving $42 million US in fuel this year by extending each flight by one to three minutes.
