Package delivery appears jollier this year - USA Today A white Christmas wasn't in the cards for most of the U.S., but that bodes well for package delivery. So does the fact that both Federal Express and UPS say they've refined their systems to help prevent missing packages. UPS reported things were "running smoothly" on Christmas Eve day and "we continue to deliver strong volume," spokeswoman Andy McGowan said in an email. "Our drivers are delivering throughout the day today and we will make every attempt to deliver all packages in time for Christmas," added McGowan. "We have worked closely with our customers to meet their needs while ensuring that our network provides reliable delivery service." But mishaps still happen.
