From a much longer UPS news release on this year's Peak Season:
UPS expects to deliver more than 630 million packages between Black Friday and New Year’s Eve, an increase of more than 10 percent over holiday deliveries last year. This UPS peak holiday shipping period includes an additional shipping day before Christmas versus 2014.
The company plans to deliver about 36 million packages on Tuesday, Dec. 22, up from 35 million last year, and double the normal daily average of 18 million deliveries. Consumers’ preference for ecommerce, coupled with the industry’s most often selected delivery solutions have driven UPS’s peak volume to all-time highs. The company tallied about 17 million deliveries on its peak delivery day just 10 years ago.
Since Christmas falls on Friday this year UPS plans for high daily residential delivery volume throughout the week. The company expects to make a record number of deliveries to residential addresses during the holiday period, up to 60 percent of all package deliveries, versus an average of 45 percent on a full-year basis
