Frequently asked questions

What is the difference between round trip and return?

They mean the same thing — travel out and back. Round trip is American usage and return is British. Airlines selling internationally use either, and some booking sites show both labels.

Is a round-trip ticket cheaper than two one-ways?

Usually yes on airlines and long-distance rail, because carriers price return travel as a single product. It is not universal — low-cost airlines often price each leg independently, so two one-ways cost the same.

What does round trip mean in computing?

It means one full request-and-response cycle between two systems. Round-trip time, or RTT, measures how long that takes, and reducing the number of round trips is a standard way to speed up networked applications.
