You really do need to tell us your origin station though. 'South

zone 3' covers such a wide area there are many different default
routes,
some of which will assume travel via zone 1.

If you travel via Zone 1 when the default is not to, do you have to do the
same to increase the fare?

People have previously reported examples of passing through OSIs within zone
1, but without the overall journey being charged as including zone 1.

I suspect the only check is the overall start and end points, and if the
time limit isn't exceeded.
