US LOW-COST carrier Florida-based Spirit Airlines has unveiled a feature on its website allowing customers to see how much of a fare comprises the cost of fuel.

"When a fare is $137 and fuel makes up $78 of that fare, customers can decide if the remaining $59 makes this a good time to buy," ATW Online reported the airline as saying.

The LCC provides a chart showing how much fuel is used per passenger for trips of various lengths operated by Spirit’s Airbus A319s with an 80% load factor. It also shows the current price of fuel and a per-passenger, per-trip fuel cost.

"Everyone sees the effect of oil price movements when they fill up their car, but rarely do customers have any idea how much of their fare is comprised of fuel cost," Spirit excutive Barry Biffle said. "With this new approach, our customers will see exactly what they are paying for in fuel rather than guessing."
