Don't know about the total boxes/packages count, but the Philadelphia hub, (Not Counting the Phila Air Port Hub, which is about the same size) has six boxlines and about 260 trucks working everyday. A quick guess would be about 300 boxes/packages per truck in and out per day. That makes 78,000 total on a normal day. Dec. 18th could be double that, or about 160,000 easy. Extra drivers, extra trucks (rentals), and full trucks (up to 500 boxes/packages in and out per truck). It does say the Philadelphia area, could be both hubs and Willow Grove. But the numbers are wrong. May be 90,000 more packages then on a normal day. That sounds more like it.
