To get the full facts then read the Mayoral Decision.

018

It is absolutely clear that Daily / 7 Day and longer Travelcards valid in
Zone 6 will be valid to Heathrow using TfL. Ditto for daily / weekly
caps covering travel to Zone 6.

What that doesn't explicitly reveal is how outboundary through fares
such as:

It really is time to ditch this overcomplicated nonsense and bring in flat
fares as is done in many other parts of the world. If it can work on the buses
it can work on TfLs tube and train lines.

Except the flat fare on a bus differs from the flat fare on the tube,
which differs from the flat fare on a train.

I don't think Sadiq can afford to have £1.50 flat fares across the whole
of the TfL empire; he can't even afford to keep his price-pledge when
part of the journey is on NR trains.

The obvious and simple solution is to make Heathow unequivocally in zone
6, except that would also be costly because:

(a) it would involve buying-out Heathrow's private infrastructure and
somehow compensating them for the lost premium fare revenue on HEx

(b) you'd lose the single-trip[1] "tourist[2] tax" which is most of what
this Byzantine fares structure at Heathrow is designed to collect

[1] It's notable that TfL is trying to spin "being able to take more
than that one single trip, for just 40p extra" as a benefit to
tourists, when all it's actually doing is bringing them under the
wing of temporary regular commuter fare structure.

[2] Which includes, specific to my last posting, Brits living
outboundary who depart Heathrow one day, and return on another.
