One area of Space Shuttle applications is an expanded crew.<ref name=orbiter>{{cite web|url=http://spaceflight.nasa.gov/shuttle/reference/basics/orbiter/index.html|archive-url=https://web.archive.org/web/20000831011229/http://spaceflight.nasa.gov/shuttle/reference/basics/orbiter/index.html|url-status=dead|archive-date=August 31, 2000|title=Human Space Flight (HSF) – Space Shuttle}}</ref> Crews of up to eight have been flown in the Orbiter, but it could have held at least a crew of ten.<ref name=orbiter/> Various proposals for filling the payload bay with additional passengers were also made as early as 1979.<ref name=reichert>{{cite web|url=http://www.spacefuture.com/archive/the_future_of_space_tourism.shtml|title=Space Future – The Future of Space Tourism|first=Peter Wainwright|last=(www.spacefuture.com)}}</ref> One proposal by [[Rockwell International|Rockwell]] provided seating for 74 passengers in the Orbiter payload bay, with support for three days in Earth orbit.<ref name=reichert/> With a smaller 64 seat orbiter, costs for the late 1980s would be around US$1.5&nbsp;million per seat per launch.<ref name=david>{{cite web|url=http://www.spacefuture.com/archive/the_space_tourist.shtml|title=Space Future – The Space Tourist|first=Peter Wainwright|last=(www.spacefuture.com)}}</ref> The Rockwell passenger module had two decks, four seats across on top and two on the bottom, including a 25-inch (63.5&nbsp;cm) wide aisle and extra storage space.<ref name=david/>

Another design was Space Habitation Design Associates 1983 proposal for 72 passengers in the Space Shuttle Payload bay.<ref name=david/> Passengers were located in 6 sections, each with windows and its own loading ramp at launch, and with seats in different configurations for launch and landing.<ref name=david/> Another proposal was based on the Spacelab habitation modules, which provided 32 seats in the payload bay in addition to those in the cockpit area.<ref name=david/>

There were some efforts to analyze commercial operation of STS.<ref>{{cite web|title=Commercial Orbital Transportation Services|url=https://www.nasa.gov/sites/default/files/files/SP-2014-617.pdf |archive-url=https://web.archive.org/web/20140606215941/http://www.nasa.gov/sites/default/files/files/SP-2014-617.pdf |archive-date=June 6, 2014 |url-status=live|date=February 2014|access-date=November 20, 2022|publisher=NASA}}</ref> Using the NASA figure for average cost to launch a Space Shuttle as of 2011 at about $450&nbsp;million per mission, <ref name="missionbudget">{{cite web |author=NASA |year=2011 |title=How much does it cost to launch a Space Shuttle? |url=http://www.nasa.gov/centers/kennedy/about/information/shuttle_faq.html#10 |url-status=dead |archive-url=https://web.archive.org/web/20221205113150/https://www.nasa.gov/centers/kennedy/about/information/shuttle_faq.html#10 |archive-date=December 5, 2022 |access-date=June 28, 2011 |publisher=NASA}}</ref> a cost per seat for a 74<ref name=rockwell74>{{cite web|title=Rockwell 74 Passenger Module|url=http://www.spacefuture.com/archive/images/the_space_tourist.15.gif|access-date=November 20, 2022}}</ref> seat module envisioned by Rockwell came to less than $6&nbsp;million, not including the regular crew. Some passenger modules used hardware similar to existing equipment, such as the tunnel,<ref name=rockwell74/> which was also needed for [[Spacehab]] and Spacelab
