USPS maintains mailpiece time delivery average of 2.7 days across the network
"The United States Postal Service reported new service delivery performance metrics through the second week of the fiscal second quarter showing Marketing Mail and Periodicals remaining consistent with first-quarter results. Scores for First-Class Mail were temporarily impacted during the week of Jan. 8-14 due to industrywide delays in both ground and air transportation following recent East Coast winter storms. These delays continue to impact middle mile transit across the network."
