Mail delivery changed with the invention of airplanes. Transportation of people, and cargo evolved. The invention of the wheel, till the invention of the modern jet. Soon rockets will carry people to other planets.

The first free-lance couriers had their expenses paid by the courier companies. As time passed, and schedules and flight became more systematic. The companies found they could offer the dream vacation to the "Free-Lance Courier".  The person   carrying the packages would share in the cost of the airline ticket, for the opportunity to travel at a discounted price. This partnership benifits both sides. The courier company pays less for transportation cost, and earns more money. The courier is able to go on their dream vacation, and purchase airfare at greatly discounted prices. The Free-Lance courier benefits greatly because the airline buy these tickets on a regular basis, and negotiate greatly reduced fares.
