For their latest Oyster advertising campaign, TfL have put up posters
at Tube stations including one that says something along the lines of
"The Big Freeze - bus fares on Oyster are charged at 2000 prices".

Now UIVMM, back in 2000, bus fares were £1 if the journey included
Zone 1 and 70p otherwise. This means that the current Oyster fare of
£1 for bus journeys within Z2-6 is a 43% increase on the equivalent
2000 fare. (FWIW I've seen the poster at several stations in Z2-6.)

Does this call for a complaint to the ASA?

Why bother? By the time the ASA gives any recommendation (if they find
in your favour), TfL will have finished its campaign anyway.
