How it was originally intended:
"Travelling
This volume of Traveller deals with the basic facts of interplanetary and interstellar travel, with the details of starships, their design, construction and operation, and with combat between spaceships.*
TRAVELLING BETWEEN WORLDS
Travellers travel. They move between worlds as well as on their surfaces. The distances such travel covers may be interplanetary or interstellar in scale.
Individuals who decide to travel to other worlds are confronted with the choice of the method and manner in which they wish to travel. Interplanetary travel is infrequent, but is possible using ship's boats, cutters, pinnaces, or other vessels. Because of the widely varying distances, a vessel must be chartered, at a price set by the referee or by the player-character who owns the vessel. Commercial travel by scheduled liner, when available, is provided at approximately 10% of the cost for similar interstellar travel.**
Interstellar travel is more rigidly defined, being divided into levels of passage with specific features and costs."
