Santa wasn't the only one racing against the clock to get packages to homes Tuesday night. UPS was too. But the company's backlog left some Americans with gifts missing from under the Christmas tree Wednesday morning. "We're terribly sorry," spokeswoman Natalie Black told CNN. In a statement, the company explained that "the volume of air packages in our system exceeded the capacity of our network immediately preceding Christmas so some shipments were delayed." "We know how hard it is for everyone to receive their holiday packages, and we're working around the clock to resolve this issue," Black said. Behind the scenes, perhaps -- but UPS stuck to its plan to make no deliveries on Christmas, angering some customers."We're terribly sorry," UPS saysThe company couldn't handle the volume of air packages it receivedUPS is not making deliveries on ChristmasAmazon refunds some shipping charges, offers gift cards
Some customers received messages from Amazon.com alerting them of the "failure in the _ transportation network."
