ATLANTA (AP) — UPS is raising ground, air and freight rates by averages of around 5 percent as it seeks to boost revenue that has stagnated this year.The Atlanta-based package delivery company said Thursday that on Oct. 26 freight rates will rise an average of 4.9 percent, and on Dec. 28, rates on ground shipping will increase 4.9 percent and air and international services will rise about 5.2 percent.United Parcel Service Inc. spokesman Steve Gaut said some large shipping customers or retail consumers could see larger or smaller increases than the averages, but he declined to give specifics. He said UPS needed the increases to cover rising labor and equipment costs and to be compensated fairly for its services.UPS will also boost surcharges for fuel and heavy packages. The fuel surcharge on ground shipments will rise from its current 4.75 percent to 5.25 percent on Nov. 2.
