However, can I just say that I am a little less certain than I
originally was on the question of whether this would be valid. I can
say with certainty that combining Travelcards *within* the London
zones is legit - i.e. a zones 1-3 Travelcard plus a zones 4-6
Travelcard. It was on this basis that I presumed that a Travelcard
from an out-boundary station (i.e. a station outside of London, such
as Cambridge) would be OK.

In your scenario I'm just a bit wary of some requirement that perhaps
the train needs to stop somewhere within zones 4-6 for the Travelcard
element to "kick-in" (as it were), so allowing you to combine more
than one Travelcard. One could argue that part of the reason for the
higher price is the non-stop express journey into Kings Cross.

I'm still tempted to think it is a valid combination, but I'd get rock-
solid confirmation of this first. I can certainly see grippers getting
fussed about it. If it is a valid combination, FCC wouldn't be keen on
the knowledge spreading, given that they'd lose money. Though indeed
if it is valid, why isn't everyone else doing it?

Perhaps some ticketing gurus might help us work out the definitive
answer to this?

I have emailed FCC to ask, although my last experience asking their
customer service team a question resulted in getting three different
answers and only getting a sensible answer when I forwarded their
nonsense to FCC's managing director.
