Airlines have been introducing various methods to reduce weight on planes in order to reduce fuel usage. In an average, a commercial airplane would burn up to a gallon of fuel every second, and fuel cost accounting for 21 cents in every dollar spent.
Following are some of the crazy ideas Airlines adopted to reduced fuel usage;
– In 1987, American Airlines saved $40,000 by removing just a single olive from each in-flight salads served .
– in 2012, Ryanair send a memo to its inflight staff to reduce weight and get slim.
– In 2008, Air Canada removed life vests from some of its aircraft in favour of lighter floatation devices on flights that didn’t venture more than 80 km from the shore.
– In 2008, Northwest Airlines saved $US500,000 a year, by slicing its limes served in soft drinks – into 16 slices instead of 10.
– In 2009, Japanese airline, All Nippon Airways asked passengers to visit the lavatory before boarding because empty bladders means lighter bladders.
– In 2013, Samoa Air introduced a “fat tax”, whereby passengers would be charged a fare according to their weight.
– In 2017, Qantas introduced new cutlery and tableware looks like stainless steel, changed the linen on board, that reduced in weight by 11 per cent. Qantas also reduced the weight of its trolley carts for international flights to just 18kg, a reduction of 7kg, and saves close to 535,000 kg per year on fuel.
– Virgin Atlantic, introduced thinner glassware, slate plates and changed its chocolate and sweet offerings to lighter versions, and altered its beverage offering for night flights, when fewer people drink. Virgin saved 53,000 litres of fuel a year on its fleet.
– United airlines reduced its inflight magazine paper weight, saving 28 grams per copy that saved $US300,000 a year.
– Irish airline reduced the size of its inflight magazine from A4 to A5 and cut the amount of ice taken on board.
– British Airways has a dedicated fuel efficiency team, that reduced the weight of its catering equipment, as well as printing its in-flight magazine on lighter paper.
– The airlines no longer prints receipts for in-flight purchases, saving it the need to carry 420,000 till rolls across its fleets.
Chief executive Chris Langton told CNN at the time: “What makes airplanes work is weight. We are not selling seats, we are selling weight.”
