Space flight activities are growing on an international level, thereby creating an evident need for a safe and efficient integration of space vehicle operations into the air traffic system. For concepts like very high-speed intercontinental passenger transport via suborbital point-2-point flights, as it is proposed by the DLR SpaceLiner, this integration issue is becoming especially relevant. As part of a case study approach to analyse the effects of space vehicle operations on air traffic and to evaluate mitigation strategies and optimized ATM integration, a traffic impact analysis has been prepared and conducted for the SpaceLiner return trajectory towards a European landing site. First results of the analysis will be presented together with the methodology and modeling approach which has been applied
