Yup, leave the hedging to the pro's. One bad contract and that Futures/options broker is out of business, as well as the person who bought the contract! I was a commodities broker out of college, but I traded LGP and fuel oil. Hedging is a very high risk investment. It usually only requires 10% down on the contract, but you lose 100% if things go wrong. Options are usually the safer way to go. The entire futures market is based upon speculation, or what the investors and traders THINK will happen in the future.
For companies like Southwest, this is very beneficial, because the bean counters can predict to a very high degree as to what their annual fuel costs will be, and once they own the fuel, they are less likely to get burned by fuel price spikes on the spot market. The downside, it requires a ton of cash up front, they have to pay to store the fuel somewhere, and if fuel prices drop below what they paid for it, they are sitting on fuel that they cannot offload.
I wouldn't recommend hedging to anyone unless you have a really good trader or broker, and you are fully prepared to toss whatever cash that you have invested when things go south.
Hope this puts it into every day terms and helps
