'Reise' and 'Busfahrt' can both refer to a route to another place. 'Reise' is general and can include many means of transport. It often refers to the whole plan: setting off, arriving, staying there, and returning. 'Busfahrt' is more specific and says that you are traveling by bus. It can be a short route in the city or a long journey. The words are easy to mix up when a trip is made by bus. In that case, 'Busfahrt' is the exact part or the exact way of getting around.
