CHICAGO, Nov. 20 (UPI) -- Chicago and some of the Windy City's inner suburbs still have the lowest performance scores for overnight mail delivery in the United States.
U.S. mail sent within the 606, 607 and 608 ZIP codes from July through September arrived the next day 94 percent of the time, the Daily Southtown of Chicago reported Tuesday.
Although that's up 3 percent from last year, the on-time delivery rate is still 1 percent below the national benchmark of 95 percent, the newspaper said, citing U.S. Postal Service figures released Monday. That puts Chicago behind New York, Detroit and Houston.
Other Chicago suburbs hit 96 percent on-time delivery and that regional improvement shows the hiring of 337 new carriers is paying off, Postal Service spokesman Mark Reynolds told the newspaper.
"We've seen a consistent trend pointing upward," Reynolds said. "We think we still can continue to make progress."
Not everyone agrees.
"It is not getting any better. If anything, it's getting worse," said Alsip Mayor Patrick Kitching, who maintains late delivery consistently ranks among the top constituent complaints.
