I was on the Circle last week and became aware of a change in the
representation of underground/NR interchanges on the in car

like Victoria provide access to National Rail you now get an
emphasis on airport connections. How long has it been like this?

It's been like this since at least September 2006, as that's when I
complained to LUL about the District Line diagram showing "Trains to
Heathrow" from Ealing Broadway, which is an advert for a rival company
(Heathrow Connect). I was triggered to do that by an anxious passenger
who had been advised correctly to change to the Piccadilly at Acton
Town, but then noticed the contrary advice on the line diagram, and
asked for my help in resolving his dilemma.
