Shuttle service to/from airport

Hi, does the school provide a shuttle service to the airport? If not, what is the safest way for my daughter to get to and from? TY

During specific events such as pre-Orientations and organized visits, WashU provides shuttles. For normal travel, options include the Metro and taxi services

My daughter went to SOAR this year and there was no shuttle provided. But she met couple of kids on the plane and they all shared a taxi together
