The travelcard is obviously zonal, but is the boundary zone 4 - Stansted
Airport zonal?
Yes.

No, a zonal ticket is one that gives you travel within a zone - usually
unrestricted travel.

The "Boundary Zone" tickets are described in the NFM (section K) as
"excess fares". Thus they are showing an excess fare rather than being a
separate ticket within the meaning of the National Conditions of
Carriage.

When travelling to somewhere that doesn't have a Boundary Zone ticket,
you get issued a normal ticket from somewhere (which *may* be the last
station within the relevant zone) and, says the manual, the normal rules
about combining tickets apply.
