An increase in the number of holiday packages this year has left parcel delivery services UPS and FedEx working to get delayed packages to their intended destinations.
According to UPS, the company's system was overwhelmed by demand; saying that there were too many boxes and not enough planes. A company spokesperson said the demand was "much greater" than originally forecast this year.
UPS has not said exactly how many packages are late, but they described the number as a "small percentage."
FedEx is also behind on its deliveries, citing bad weather, an increase in online shopping and fewer shopping days between Thanksgiving and Christmas as the primary reasons. Some FedEx customers were able to pick up packages at their local FedEx Express centers on Christmas.
Both FedEx and UPS will start delivering again today.
