Delivery reliability improved for the agency’s Ground Advantage product but faltered for most other categories, per a report from the USPS Office of Inspector General.
- The U.S. Postal Service struggled meeting on-time delivery goals during the 2024 peak season despite lowering its performance targets, according to a July 21 report from the agency’s Office of Inspector General.
- Service levels were hurt in part by the Postal Service not accurately anticipating how much package volumes would increase during the peak season, per the OIG. During the peak, volume for package shipping services increased from the previous peak, driven by significant growth in Ground Advantage demand.
- “Specifically, in certain markets it had to purchase extra transportation to move mail from over-capacity processing facilities and over-filled planes,” the OIG said. USPS air cargo volume exceeded air container capacity every week of peak, it added.
