Do Cargo fly very short routes? Let's say that a package has to travel from point A to point B. These places are not located in the same Country, nor are such Countries adjacent to each other. Example: point A is in Italy, point B is in the United Kingdom.

The package is not delivered directly. From tracking info made available by the Company, you find out the package leaves point A and reaches Rome. Then it reaches Bologna, and later Dusseldorf, Germany. It then reaches Barking, in the United Kingdom. From here, it reaches Tamworth and then gets delivered to point B. These legs are pretty short, if you map them, so my question is: 

could the package have traveled by air in any of such legs? or do Cargo companies prefer other means in this situation?

EDIT

I am not referring to the use of wide body aircraft on short-haul. Rather, I want to figure out if contracting out the delivery of goods over short-haul routes is a common practice among Cargo airlines. If this is true, how could a given package remain within the network of the Company?
It's fairly common for cargo, freight, and mail to be carried by aircraft - particularly for high value or priority cargo.

For example Royal Mail (the primary British mail service) uses short haul flights for distances of less than 100 miles (London Stansted to East Midlands Airport), along with around another 10 flights within the UK, every night.

These flights are used for priority (next day) mail, but will be filled with "cheaper" mail if necessary.

It all depends on the value of the cargo and the speed which it needs to travel, and aircraft only tend to be used where it is profitable to do so (ie where the cargo needs to travel fairly quickly and they can charge a high price to justify that).

Generally trucks will be used for shorter distances (&lt;500 miles) for low value cargo, and for longer distances for heavier cargo or cargo which does not need to travel quickly.
