Mark Brader:
Where'd you make up that number from? It says here

http://www.tfl.gov.uk/assets/downloa...April-2007.pdf

that a single ride with OysterCard varies from £1.50 within Zone 1
(i.e. Central London) to £3.50 if you go from Zone 6 (i.e. Heathrow)
to Zone 1.

Bob Wood:
It also says that that same journey will cost only £2 outwith the hours
of 07:00 to 19:00 on Mondays to Fridays.

So it does! Thanks, I hadn't heard about that reduction. Still, there's
a large time interval when the higher fare applies.
