"No surprise fees." Those are the first words you'll notice when you visit Southwest Airline's Web site.
It's a declaration that puts Southwest in a class by itself today, as most airlines are doing everything they can to make money while fuel prices rise to new heights.
While other carriers are parking planes, cutting staff and tacking on fees in a desperate attempt to balance the books, Southwest has, in many ways, dodged the crisis. The carrier hasn't added fees. It hasn't cut capacity. It hasn't grounded planes.

Southwest can declare that "Fees don't fly with us" because the carrier made a business move that has paid off dramatically. Today, while much of the competition struggles to pay for jet fuel, Southwest buys 70 percent of its oil at approximately $51 per barrel, a significant savings over the going price of more than $130 a barrel.
The practice, called hedging, allows carriers to put in money up front to secure a set fuel price. For Southwest, it has really paid off, sheltering the airline from steep oil price increases that are hurting other carriers. The Air Transport Association estimates that the airlines will pay a $61.2 billion fuel bill this year, up from $41.2 billion last year.
Airlines are even scrambling to remove any bit of extra weight from their planes to save on fuel costs: American is using lighter food carts; Delta jets have less water in the toilets and bathrooms; and Northwest is trimming the size of the inflight magazine.
But according to aviation consultant Michael Boyd of The Boyd Group, the unprecedented price of fuel means the little things carriers are doing to save money are not enough.
"This is not a situation where we have to adjust," Boyd said. "This is a situation where we have to totally rebuild the industry."
Meantime, at Southwest, an earlier investment in fuel at a lower price has given the carrier a leg up on the competition.
"We paid the money to have that coverage in place, and absolutely it is providing us tremendous protection right now," said Southwest CEO Gary Kelly.
"Without that, all else being equal, we would be losing money like every other airline this year," Kelly said. "So it keeps us in the black. This year alone, it is going to save us $2 billion."
"Southwest was the only one with the foresight, and the only one with the cash," said David Field, U.S. editor of Airline Business Magazine.
Still, according to aviatian experts, the carrier is struggling despite the lower price it pays for most of its fuel.
"Southwest, even though it's hedged, isn't making money on its flights," Field said. "It's only because the hedging, the buying, the locking in of low-cost contracts, it's only because of the hedging that Southwest was able to make a relatively small profit."
In 2009, only 55 percent of Southwest's oil is hedged at $51 a barrel, and the amount drops off further over the following years.
"The reason Southwest has made money for the last year is because they're really so good on their fuel hedges," said aviation economist Darryl Jenkins. "These are expiring, they will never get fuel hedges as good as they had in the past, so what they're going to be able to do in the future is a totally different matter."
In the meantime, Jenkins said, Southwest is in a better position than most.
"I think the statement may well be they were the luckiest people on the block to figure out where the price of jet fuel is going," Jenkins said.
"Fuel is such a big piece of our operating expenses, it's just like driving your car," said Southwest's executive vice president and chief operating officer Mike Van de Ven. "If you could get better fuel efficiency out of your vehicle, it is more money in your pocket. It's more money in our pockets, it's more money in our customer's pockets."
