Save on weight means save on gas. Multiply that by thousands of flights and it adds up. United printed their in flight magazines on lighter paper and saved hundreds of thousands of dollars, just by using thinner paper.
They only eliminated 5kg per 737, but that added up to $290k savings.
If anything I think it’d be even more effective on longer flights as those jets spend more time in cruise vs short haul airliners.
By using lighter paper to print their in-flight magazine, Hemisphere, United Airlines saves up to 170,000 gallons of fuel, which cuts about $290,000 in annual fuel costs.
One magazine is now one 29 g lighter and weights 195 g which will make a usual 737 plane that carries 179 passengers 5 kg lighter on average.
