"So far, space tourism has been the territory of smaller start-ups such as Space Adventures and Armadillo Aerospace. (Richard Branson's Virgin Galactic is a high-profile player in the game, but the flights his company sells do not reach orbit.) Boeing's participation lends some corporate muscle to the private-spaceflight business, but its proposed contributions are still sketchy. A joint press release from Boeing and Space Adventures trumpets only an agreement to sell 'anticipated transportation services' to private individuals, companies and even U.S. government agencies other than NASA."
