UPS expects to deliver 527 million packages between Thanksgiving and Christmas this year, surpassing last year's record high by 10 percent.
The world's largest package delivery company estimates 28 million of those will be delivered on Thursday, Dec. 20 -- projected to be the busiest day of the year.
That's nearly double what the Atlanta company moves on an average day.
To handle the big jump, UPS plans to hire 55,000 seasonal workers to sort, load and deliver packages. That's the same number it hired last year.
