A round trip could simply be a trip to and from a single place, or it could include multiple stops before reaching a conclusion back at the starting point.
Travelers and travel services use the term to describe a full trip instead of one or more one-way trips.
Travelers can typically save money by booking a round-trip ticket, instead of two or more one-way tickets.
Travel services sometimes impose minimum and/or maximum limitations on the number of days you can use to complete a round trip.
Travel services will typically list "round trip" or "RT" next to such fares. It's always best to ask if you are unsure exactly what a price quote covers.
