One of the trucks I loaded today had 10 pieces of Next Day Air (not Savers) for a single stop PAL'd to 78xx. At first I thought wtf... but then I noticed that the NDA labels were covering up 2-day air labels. It seems like the service level was upgraded? Why would this happen, and was this initiated by the shipper or by UPS? And why was it sequenced to the 7000 shelf? If the 1030 time commitment wasn't important, I imagine it should have been upgraded to NDA Saver. I went ahead and put them all on the 1000 shelf for the driver to see, anyway, just in case.
