“If you can take a kilogram out of the weight of an aircraft, that equates to about a million dollars of fuel saving over the life of the aircraft,” Sam Riggall says from his office in Melbourne ... . This is hard to believe. Checking online I get a number of 35000 flights for the life of a 747. So that makes about $30 per kilogram per flight in fuel. So a lightweight 50 kg passenger uses about $1500 in fuel per flight, even without luggage. Am I missing something here?
