That's all well and good, but as Zorry pointed out, how fast can your carrier adjust to a sudden fuel price spike?
When I was in LTL, Con-Way Central Express adopted a FSC program. This was in the late 80's. It was similar to what other large LTL carriers used. At that time the purpose of a fuel surcharge program was to cover the cost of fuel due to the volatile nature of the pump price of fuel. Customers were more understanding when it came to paying an fsc that was adjusted weekly rather than pay an across the board tariff increase. It was also simpler for the carrier to use an adjustable fuel surcharge rather than changing their published tariffs constantly. Today I believe many carriers are using fsc as a profit center. This may be because they believe the customer is still more willing to pay an adjustable fsc than a wholesale rate increase. It's a psychological thing.
