If you go to the Apple page and click on the Track Shipment you'll arrive at the UPS site.
In the top box, under the scheduled delivery date you'll see "send updates" box.
Click on that and tick the "one time only update" button, making sure your details are filled in (they probably will be) then click on the update button and you'll receive an email.
In that email it'll give much more detail. Particularly important is that it will define whether the last scan was an arrival scan or a departure scan. If it's a departure scan it'll have a time stamp. That will tell you roughly what time it left on a flight (if it has).
On a UPS flight the flight number is the UPS route number (in my case UPS11) dropping the "UPS" and replacing it with 5X. So my flight number is 5X11. You can then search for that flight number on Flightradar24 or similar.
You can find the UPS route number in UPS documentation on the tinterweb by searching for UPS routes from CLK.
