While most large dailies are struggling to hold on to print subscribers and newsstand sales, USA Today is being hurt by a drop in traffic at airports and hotels, the newspaper's mainstay. It also increased the price of single copies to $1 from 75 cents last December. In a memo to staff Friday, USA Today publisher David Hunke said the average circulation at the Gannett Co.-owned newspaper was 1.88 million from April through September. That marks a loss of 398,000 copies, or 17 percent, from the same period the year before at the newspaper, which is printed on weekdays only.
