Please, how do native name the pair of tickets people use to buy when making a trip by plane, bus or train?
The "going out" and the "coming back" tickets?
I saw many entries of that on the Internet and I wonder if it's a natural and correct way to speak.
A ticket to a destination is a single ticket, whether it is going to a place or coming back from a place.
A ticket that includes both journeys is a return ticket.
