■Abstract: Our core business is to train Space Flight Attendants (SFAs) to accompany individuals on private space travel and to provide full support to these individuals throughout the space travel process, including the preparations before and afterwards. In 2021, private spacecraft developers began enhancing ballistic space travel. In papers presented at the 2020-2021 IAC, we discussed the support to be provided by space flight attendants (SFAs) on short-distance space trips on small spacecraft. We also touched on the future potential of SFAs. In this study, we analyzed the role that SFAs will need to play in long-distance space travel. The value that can be added by and content of services to be provided by the SFAs will be discussed in terms of support and tour services for long-distance space travel. Support for passenger needs, physical and mental health care, entertainment, and a wide variety of other roles will also be examined.
