UPS will add flights out of San Bernardino International Airport (SBD) in California to cover the peak season rush in demand.

From December, the US express operator will operate four flights per week from between the airport and UPS' Louisville hub using a Boeing 757 aircraft.

President of UPS’ South California District Tom Cuce said: “This is our busiest time of year, and with the huge spike in holiday shipments, we need additional capacity to deliver for our customers.

"The flights from SBD will fly directly to Worldport, our main air hub in Louisville, connecting the Inland Empire to UPS’s worldwide network.

UPS expects to deliver more than 700m packages globally between Thanksgiving and Christmas Eve, a 14% increase over 2015.

The airport boasts a new air cargo facility located adjacent to 60 acres of aircraft ramp, and access to three major interstate highways.

"In recent years, SBD has made key investments to support air cargo activities which include tremendous expansion and development potential; SBD offers a competitive environment for air cargo companies and freight forwarders looking to grow their presence in Southern California," the airport said.
