The fuel surcharge is to account for the extra cost of the fuel. Pilots ask for directs to improve efficiency and save time. It saves costs which eventually saves airfares. You compare costs to last years operation...and find your eyes popping out! Somebody, somewhere along the line, is overdoing it financially. That is why surcharges exist. If your raw material (fuel) goes up astronomically, you cannot price your tickets at the same level.
Ummmm, Wow! Exactly correct!
