Single transfer

Hi,
If a "single transfer" is a ticket of leaving (e.g. a subway single transfer), so how do we call a ticket to go and come back? Is it a "return ticket"/ "A round trip ticket" ?
Here's what I usually say and hear.
a one-way ticket.
a return ticket
a round-trip ticket

And is this name used for a flight trip, bus and subway? Yes, except m

Hi, Clive.

Thanks. Is there any difference between an "one-way ticket" and a "single transfer" ticket? Or are they synonyms? Because I've heard that a "single transfer" is a ticket of leaving with connection.

Thanks,
Rose

I really don't know.

Looks like a bad translation.
In England a "one way" is also called a "single".

Thanks,

Hi,
Possibly, yes.

Hi Bokeh!

But in England this "one-way ticket" also includes a connection/connexion?

Best wishes,

If you get on the London Metro (Tube) going from point A to point B, needing to change trains several times that is still known as a "single".
