What logistical burden did the extended Starliner stay place on the International Space Station (ISS)?

Complicating the crew rotation schedule for future missions

The extended presence of Wilmore and Williams aboard Starliner, which was safely docked to the ISS, created several unplanned logistical strains on the orbital outpost. While the station is designed to handle temporary overages, an indefinite extension consumes resources and, more significantly, complicates scheduling. Specifically, every day the crew remained attached meant they were tying up a valuable docking port. This directly impacted subsequent crew rotations, such as potentially creating a cascade effect for the following Crew-9 rotation or delaying other scheduled arrivals, thereby complicating the overall logistics plan for future missions dependent on port availability.
