Now I understand what you're planning on doing - i.e. heading to
Tilbury for a boat, rather than staying there - I can see where you're
coming from here (metaphorically speaking, of course - I know you're
actually coming from NYC!).

Yes, an off-peak Tube journey (that's after 09:30 but before 16:00
weekdays) from Heathrow to either Tower Hill (for Fenchurch St) or
Upminster would indeed currently cost GBP2.40 (that's a zones 1-6
journey).

As you say, a single from Upminster to Tilbury is GBP3.00 - from
Fenchurch Street it would cost more than double, at GBP6.20. So by
staying on the Underground all the way to Upminster, you would indeed
save money (you'd pay for zones 6 to 1 regardless, so going out the
other side of z1 back to z6 - i.e. Upminster - is already paid for, as
it were). The quid-pro-quo is that the journey on the District line
takes a bit longer. But you also get a bit of local east London
flavour this way!

Must admit I simply hadn't considered staying on the District out to
Upminster - but actually it works out quite well.
