N9 night busorRailAir RA1?

The short answer

These do not go to the same place, so price is not the comparison. The N9 night bus reaches Paddington, and the whole of Zone 1 beyond it; the RailAir RA1 does not. Reading is a separate town on the main line west, not part of central London.

The RailAir RA1 is quicker: 40 min against 1 h 22. The N9 night bus varies between 79 and 89 minutes.

N9 night bus: 23:43–04:45. RailAir RA1: 04:10–00:15.

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.

Reading to Heathrow is billed "in 40 minutes" on RailAir's own site and "under 45 minutes" to Terminal 5 specifically — book the extra few minutes for T5.

It does not run around the clock: the last coach from Terminal 3 is 00:15 and the first is 04:10, a gap of almost four hours.
