fuel surcharges

As of Monday, the average cost of a gallon of regular fuel is now $4.325, according to AAA. Both ride-share companies say they're adding surcharges to deal with the spike in gas prices in the U.S.

Airlines have been paying the lowest prices in years for jet fuel. Nevertheless, fares are rising and many fuel surcharge fees remain. Traveler advocates are angry but airlines say labor costs are up.
