Thousands of holiday gifts sent via UPS have been delayed and may not arrive by Christmas. The delays are not necessarily weather related. The world's largest package delivery service says it has been overwhelmed by volume.
Saying in a statement: "The volume of air packages in our system exceeded the capacity of our network, as demand was much greater than the forecast."
The company says workers at its hub in Louisville are working through the holiday to catch up.
