'Economic' Air Travel

Given the ever increasing fuel prices, the air fares have skyrocketed to as high as the aircrafts flying in the air. It has become increasingly important to think about how to make our air travels more economical, to get more value for money. Adverse situations call for unique measures, and after much thought, I have concluded that the following will make air travels worth every penny:

1. Carry baggage which weighs just under, or is exactly, the maximum limit allowed.
2. Put on weight. More weight = more fuel burnt to transport me from Point A to Point B = more value for money.
