Graham Murray remarked:
The interesting sociological experiment will be whether HAL treat the Elizabeth Line
like the tube, or like HC.

In what sense does it treat the Tube and HC differently now?

Oyster (at least PAYG) is not available on HC to the airport, only to
Hayes & Harlington.

That's a TfL decision, not the airport's.

With the fees for using the link being fixed (see my reply to Recliner)
it seems disingenuous for TfL to price gouge travellers between H&H and
LHR "because they can" when the costs to TfL are the same whether or not
the trains are full or empty.
