Just shooting in the dark, but if they are predominantly shipped by aircraft, but some are shipped by other methods (actual ship?) then you could see a larger overall percentage of reduction if you examine just the aircraft shipments.

exramoore is correct.

They have a brief explanation using other products here
http://www.apple.com/environment/#transportation

Smaller packaging.
Apple employs teams of design and engineering experts who develop product packaging that’s slim and light yet protective. Efficient packaging design not only reduces materials and waste, it also helps reduce the emissions produced during transportation.

For example, the packaging for iPhone 4 is 42 percent smaller than for the original iPhone shipped in 2007. That means that 80 percent more iPhone 4 boxes fit on each shipping pallet, more pallets fit on each boat and plane, and fewer boats and planes are used — resulting in fewer CO2 emissions.

There is this quote:
Packaging volumes reduced by 25 percent for up to a 45 percent reduction in aircraft usage.

My question is:
How would a 25% reduction in volume convert to a 45% reduction in airplane usage?

Probably related to the rounded fuselage. With a thinner box you can use more of the curved edge space that used to be wasted.

I think it just means they can fit more computers on a single shipment from China because they can pile more devices onto a shipping pallet. Height and width of the cargo area is the limitation. Shippers don't ship bulk materials loose. They are stacked and sealed onto pallets.
