Postal Service moves half of long-distance mail by air just to satisfy UPS contract

An audit reveals that the Postal Service is flying half of its long-distance mail to meet UPS contract obligations, despite its official policy favoring surface transportation. This move comes due to lower parcel volumes and the need to avoid penalties for missing UPS volume guarantees. This shift highlights the tension between contractual obligations and operational policies, potentially impacting efficiency and costs. The implications could reshape logistics strategies and fuel debates about the future of postal services and their partnerships.
