Sagittarian Spaceways is presumed to be one of several spacelines of the Twelve Colonies prior to their destruction. Pan Galactic and Intersun are other spacelines.
There are two known models of ships that Sagitarrian Spaceways has built from the Intersun Passenger Cruiser standard model.
SSPL-379A
It is visually apparent that both of these models have different color schemes. By the model name, it would be assumed that this ship would have a lower passenger capacity than its SSPL-481A counterpart.
SSPL-481A
This ship has, only by its name, may be assumed that it would have a higher passenger capacity than the 379A model, or would have been a later model that has been improved from the original one but having the same seating capacity.
