Let me try to explain more simply.
More equipment on board = more weight.
More weight = more gas usage
more gas usage = need more fuel, and thus uses more fuel to carry the weight of the additional fuel.
Did you know that airliners always have to find a "balance" when painting their planes?
Paint can weight a few hundread kilograms in a large plane (Iv'e seen the number of 500Kg or half ton in a 747-200 around the web).
That also "costs" to the airline in fuel. but int he other hand.. Paint protects the fuselage from corrosion and "bounces" light that can radiate in the plane (and thus increase AC costs).
Thats why some airlines either go for white paint, or metal brushing finish (like American Airlines and AeroMexico).
Yes, thus the usage of more efficient high-bypass turbofan engines, American Airlines lack of paint, and even them eliminating one black olive from all salads back in about '87 saved them around $40,000.
And, on the tail of that, and relating back to Schlotzsky's earlier, one of the ways they saved money on the black olives they put on their sandwiches was to contract with a company that pitted and canned olives...they simply got a very discounted rate on the ends of the olives that were being pitted and normally just being discarded. Brilliant.!!!
