This interesting article from Bloomberg shows how air freight has suffered from smaller volumes, as the parts and packaging used in high-tech goods shrink. The iPhone’s package volume reduced 42% between 2007 and 2011 – effectively saving one 747 trip per every 371,250 units. At some point, carriers will need to change the way they charge, says an analyst. But there is some good news for airlines – parts can’t shrink much more, and the swift advances in technology mean there will always be another product out soon.
