Hi all,

Just trying to work out what the best way of doing Central London to
Heathrow Airport on Oyster PAYG is (without using Piccadilly line).

I heard that there was a bus from Hayes/Harlington so might be worth
taking FGW or Heathrow Connect (interestingly their website says PAYG
not valid but the map seems to disagree) to there before changing.

Any better ways?

It depends on (a) where in Central London you are starting from, (b)
which terminal you are heading for at Heathrow, and (c) what you mean by
"better". (Faster? Cheaper? Fewer changes?) Why don't you want to use
the Piccadilly Line?

Heathrow Connect's website says that "Pre-pay Oyster" is not valid,
which suggests that it might be an old comment that hasn't been revised.
TfL's site says that PAYG is valid between Greenford/West Drayton and
Paddington, which would include the section of HC east of Hayes. I've
emailed HC for clarification.
