It only exists at night. Between 04:45 and 23:43 there is no N9, and this is the only option here that runs in the small hours at all.

It is slow: 82 minutes to Piccadilly Circus against the Express's 15 to Paddington. You are trading an hour for £24.25.

It runs every night of the week, unlike the Night Tube, which runs on Friday and Saturday nights only.

£26.00 against £5.90 on the Underground is 4.4 times the fare to save about 35 minutes — roughly £34 an hour, before you count what the cap would have saved you.

It does not count towards the daily cap. TfL states that Heathrow Express journeys "are not included in caps and Travelcards", so a same-day return is £52.00 and caps at nothing.

It goes to Paddington and nowhere else. If Paddington is not your destination, add a further journey and its fare to everything above.

Terminal 5 adds five or six minutes to the quoted fifteen — the operator says six, the airport says five.

The first departure from the airport is not stated here: the operator publishes the first train from Paddington at 04:34 Monday to Saturday and the last from Terminal 5 at 23:57, but does not publish a first departure from the airport itself.
