Very official Boeing news release (747 Fun Facts): "For a typical international flight, one 747 operator uses about 5.5 tons (5,000 kg) of food supplies and more than 50,000 in-flight service items."
This is not as funny... 5,000 kgs of food mean for 500 passengers (crew included) 10 kgs of food per passenger... Of course, you don't eat and drink 10 kgs of food during a flight of 10 to 15 hours... If you knew before your journey what you want to eat and to drink (here you can apply computer technology at the booking of a flight) you wouldn't need a menu and only 5 kgs of food would be plenty for one passenger...
The above measure could result in a weight reduction of 2,500 kgs of the airliner... I think 2,500 kgs can be translated into 25 average passengers with seats... The only question remaining is: where can you seat 25 more passengers?
The answer: you can seat the additional 25 passengers on another Boeing 747-8 Intercontinental... 20 "fit flights" (with reduced food on board) could allow 500 additional passengers - that is the full capacity of a new Boeing 747-8 Intercontinental... According to this calculation "fit flights" could result in major benefits for The Boeing Company, the operators of the Jumbo Jet and the passengers of the airlines...
Best wishes, Joseph de la Mikula and Team
