roundtrips

Round trips refer to journeys or operations that begin and end at the same location, with a distinct outbound leg. In travel and transportation, a round-trip ticket covers both the outward journey and the return. Round trips are often marketed as cheaper than purchasing two one-way tickets and may offer more schedule flexibility; however, restrictions on changes, refunds, or mileage accrual vary by carrier and fare class.

In computing and networking, round-trip time (RTT) measures the time it takes for a signal to travel from its origin to a destination and back. RTT is a key latency metric used to assess performance of networks, applications, and internet connections. It is influenced by physical distance, routing, processing delays, and congestion, and is typically estimated with utilities such as ping or traceroute.

In logistics and supply chains, round trips can refer to a vehicle route that begins at a depot, services several locations, and returns to the depot, or to a backhaul that completes the cycle.

In planning and analysis, round trips are used as a simple model of cyclic operations, enabling comparisons of cost, time, reliability, and risk between a round-trip option and alternatives.
