How to lower airplane's fuel consumption

Gas prices never stop climbing. What will we do to contributes the problems of fuel consumption? Airliners are desperate to find ways to lower the consumption of gasoline and I think they find a remedy to consume less fuel while flying.

Instructions

Difficulty: Moderately Easy

1. Airplanes used too much gasoline or fuel and some of these planes are flying without passengers so the lose is double. But you can help to save gasoline in flying by taking bath, not you but the plane. Wash the airplane real good or clean it thoroughly so that it will not consume the gasoline quickly.
   
   If our body needs water to cool off when we are hot then airplanes just like that.
2. When you fly, try to bring light luggage so that the airplane will not heavily loaded with so much cargoes and makes the plane consume more fuel compare to the one flight that has no passengers.
3. Make the airplane colorless to reduce the weight. The more color you add into it the heavier it will be.
4. As a passengers, do not eat and drink too much before boarding the plane so that you will not add more heavy weight on the plane.
   
   Another thing is, if you can make the luggage floats inside the plane that would be helpful too.
   
   Did you see how spaceship or space shuttle works inside, scientists are floating ,so if you can invent an airplane that you do not need to sit down in the seat that would be great.
5. The airplane should not be made with heavy materials so that it will not be that heavy to fly. The seats should be lighter than the person sitting on it.
6. Save fuel or gasoline as you can, not just by flying with an airplane but also in your driving behavior.
