What is 'one return trip'?

Question

Is tht ONE way to the location or both back and forth?

Answer 1

It's one trip, from where you are, to where you're going, and back again to where you started.

Answer 2

one way get's you there.. round-trip is there and back..

I just bought a one way to SF because I'll be picking up a car and driving back, or if you were going somewhere and not coming back at all you wouldn't need a round-trip...
