Washington, Sep 16 (DPA) Houston-based Boeing Company Wednesday said it has a tentative agreement with Space Adventures Ltd to provide seats for private passengers into outer space.

The seats would be on board its CST-100 spacecraft, which it is developing under NASAs push for commercial crew spacecraft. The CST-100 could carry seven people and fly on multiple launch vehicles.

The craft is expected to be operational by 2015, Boeing said in a statement on its website.

Virginia-based Space Adventure has brokered seats for seven people on eight flights to the orbiting International Space Station, each at a cost of millions of dollars, mostly on board Russian spacecraft.

No price has been set for the Boeing flights.
