UPS expected to have busiest day of the year Tuesday

Tuesday is one of the busiest days of the year for UPS deliveries, with more than 36 million packages expected to be delivered. That's more than double the volume of a typical UPS delivery day.

Many people are anxious their packages will still be in trucks and not under trees this Christmas though.

"They told me it was supposed to get here last week, but I'm still waiting for it," says Marco Medina.

Medina's package is one of the 630 million packages UPS expects to deliver between Black Friday and New Years Eve.

"This is by far the busiest holiday season we've seen," says Penske's South West Area Vice President Art Narmi.

It's busier by ten percent from last year, according to UPS.

"It's really economy wide, there is a burst of activity that flows through the end of the year," says Narmi.

UPS is relying on partners like Penske to help them meet deadlines. They rent thousands of their trucks nationwide, and hire roughly 95.000 temporary workers.

More resources that online shoppers hope translates to getting packages before Christmas morning.

"I''m hoping we can get it. I hoping that when I get home it will be there," says Nazareth Terrazas.
