The direct link between Heathrow and Reading is the RailAir RA1 bus, running from £13.60 one-way, departing up to every 20 minutes and reaching Heathrow in around 40 minutes. It calls at all three passenger terminals, T2, T3 and T5, so there's no need to change or travel via London first. A taxi covers the same roughly 26-mile route door to door for an indicative £70 to £85. Checked 2026.
RailAir RA1: the direct bus
RailAir is a National Express-operated coach brand built specifically to link Heathrow with nearby rail towns, and RA1 is its Reading service. It departs Reading Railway Station up to every 20 minutes and reaches Heathrow in around 40 minutes, calling at Terminal 3 (Level 0, Arrivals, Stops 7-8), Terminal 2 (Level 0, Stops 11-12) and Terminal 5 (Arrivals forecourt, Stop 9), with a stop at Winnersh Triangle along the way. Services run from around 04:10 to past 23:00, so it covers early departures and late arrivals, not just a daytime timetable.
Fares start from £13.60 one-way, and tickets are valid from whichever Heathrow terminal suits your flight, so you're not locked into a specific one at booking. RailAir also runs family and group discounts: the third and fourth adult in a group travel free, and all children under 16 go free, worth checking at booking if you're not travelling solo.

Taxi: door to door
A taxi or pre-booked private hire takes you directly to a Reading address rather than the railway station, which matters if your destination is well outside the town centre. The indicative fare is £70 to £85 for the 35-to-50-minute road journey, though as with routes beyond Heathrow's busiest destinations this figure is indicative rather than fixed, so confirm the exact price with your operator when you book. A pre-booked minicab that fixes the fare and tracks your flight removes any risk of a surge charge if you land late.
Why RailAir beats going via London
Reading sits on the Great Western main line out of Paddington, so in theory you could take the Elizabeth line or Heathrow Express into London and change onto a Great Western Railway service back out to Reading. In practice this takes longer overall than RailAir's direct 40-minute run, since you'd be travelling into London before doubling back west, changing stations with your luggage along the way. RailAir is the more direct option unless London itself is also part of your journey that day.
Comparing the options
| Option | Fare | Time | Notes |
|---|---|---|---|
| RailAir RA1 | from £13.60 | ~40 min | Direct, up to every 20 min, all three terminals |
| Taxi / pre-booked minicab | £70 to £85 indicative | 35 to 50 min | Door to door, confirm fare when booking |
| Rail via Paddington | Combined fares | Longer overall | Only sensible if London is also on your route |
Which to choose
For most solo and paired travellers, RailAir is the simplest and cheapest way between Heathrow and Reading, running frequently enough that you rarely need to plan far ahead. A taxi is worth the extra cost for a group with heavy luggage splitting the fare, for a Reading address away from the station, or for a very early or late arrival if RailAir's overnight gap doesn't line up with your flight.
