I wonder why airlines did not implement these fuel saving measures from the get go. Some of the changed mentioned in this article seem to be common sense - don't carry unnecessary loads over *any* distance, maintain a balance between customer comfort and fuel efficiency, etc, etc. Regardless, it's never too late to save fuel; you can reduce your car's fuel consumption by monitoring a few things too:
1. Ensure your car's tires (tyres for the British in us) are filled to the optimum level (32/32 for most US cars)
2. Get regular oil changes
3. Remove stuff from your car's boot (I should do this)
4. Ask your mechanic to ensure that the car's spark plugs are firing optimally
Each of these measures is supposed to increase your car's mileage by up to 1 mile per gallon.
5. Last but not least, ride the bus, train, your bicycle or with a friend :))
