I often wonder why, with the abundance of idle jumbo aircraft Qantas has, why AusPost does not increase their charter of sole purpose (freight) flights to (say) the USA.

A 747 freighter can carry over 100 tonnes of freight and at around the AusPost charge of $20 per kg that would be over $2 million income generate by packages on the flight.   A multiple of several times what it would cost to operate the flight.

There would of course be revenue on the return flight.
