Christmas & bank holidays

These dates are not the usual timetable for the day they fall on. They come from the operator’s published data, which for Christmas and New Year is often late or incomplete, so check with Transport UK before you travel. Everything above is an ordinary week.

Not published yet: Christmas Eve, Christmas Day, Boxing Day, 27 December, 28 December, 29 December, 30 December, New Year's Eve, New Year's Day and 2 January. Operators often publish festive timetables only a few weeks ahead, so check again nearer the date.

How busy is route H20?

897,598 passenger journeys were recorded on route H20 in 2024/25 across 341,370 kilometres operated. That is down from a peak of 1.21m in 2018/19.

Millions of passenger journeys per financial year, from Transport for London's published bus statistics. A passenger journey is one boarding of one bus — someone commuting five days a week makes ten of them, so this is not a count of people. Years marked 53w ran 53 weeks rather than 52, so they sit about 2% high against their neighbours. TfL changed how boardings were estimated in 2017 and restated 2016/17 on the new basis; the chart uses the restated figure, so years before 2016/17 are not exactly comparable with those after. Route-level totals do not sum to TfL's network figures, which carry separate adjustments. Powered by TfL Open Data. Compare every London route →
