Space tourism is en vogue again. Hypersonic flights have come within reach to facilitate the development of commercial point to point suborbital flights. Connecting high density poles on the continents in less than 90 min flight-time is the goal set for the SpaceLiner which is under investigation since 2005 by DLR the German Aerospace Agency. No stewards, no windows, hypersonic speed, up to 10G loads at launch and microgravity at the edge of space. These are the conditions in which the task is to setup the interior layout, design the passenger seating Unit and analyze the process from check in to check out to fulfill the extreme inflight requirements, passenger safety and comfort and transcend air travel as known today. A long and tedious astronaut-s training is not required to take a seat on board and take off. The goal is to present the evolution of commercial hypersonic suborbital point to point spaceflights, spaceplanes under development and to design an ergonomic passenger Unit as a futuristic yet feasible adaptation of airborne seatings. After studying the benchmark in the commercial suborbital tourism industry, analyzing the safety requirements and focusing on the passenger as fortunate early adopter, designs suggestions for confined spaces with high density of technology, and use of new composite materials can be expected for designing and manufacturing of the Unit which will welcome, secure and entertain the passenger during flights on the SpaceLiner.
