United is launching additional widebody flights between San Juan and its New York/New Jersey hub, while DHL is expanding its San Juan warehouse to offer increased capacity for the handling of shipments that require strict temperature controls. The effort is aimed at Puerto Rico's life sciences and pharmaceutical industries. DHL will divide its current 5,616 square-foot facility in San Juan into three independently operated cold chambers, with combined capacity of 324 pallets using single pallet racks, or 486 on double-deep racks. Each of the chambers will operate at 59-77 degrees F, and have 100-percent-redundant refrigeration systems. The chambers will also have a hot gas injection system to maintain required relative humidity levels during operation. Beginning on Dec. 18, 2016, United will increase widebody service between San Juan's Luis Munoz Marin Airport and Newark Liberty International Airport from one to six flights weekly, utilizing Boeing 777 aircraft.
