When was the last time you ordered something that didn’t come with free or expedited shipping (or both)? The rise of consumer expectations for expediency and immediate gratification isn’t likely to slow down soon, and the strain those expectations put on supply chain and fulfilment operations is immense.
Something has to give, and it’s probably not going to be consumers suddenly deciding they’re fine to pay more or wait longer to get what they ordered. The answer? Size.
The space available in the cargo bay of an aircraft or in a freight container isn’t getting bigger. That means that the individual shipments within them need to get smaller. Inch by inch, they need to make room for other packages so that everyone gets what they want, when they want it.
