| Option | Journey time | Typical cost | Good to know |
|---|---|---|---|
| RA1 RailAir coach | from about 40 min | from £24 online | Direct from Reading station to T2, T3 and T5. It has dedicated luggage space; road traffic still affects the arrival time. |
| Train via Hayes & Harlington | around 1 hour | Check live rail fare | Travel east from Reading, then change for a Heathrow-bound Elizabeth line train. Check whether its branch serves T4 or T5. |
| Taxi / minicab | about 35–60 min | Check live local fare | Direct via the M4. Ask whether the £7 Heathrow terminal charge is included. |
| Fixed-fare transfer | about 35–60 min | Live quote | Useful for an address away from Reading station or a journey outside the useful coach schedule. Compare the full vehicle price. |
Distance: about 26 miles. RA1 serves T2 at stops 11–12, T3 at stops 7–8 and T5 at stop 9. It does not serve T4 directly. RailAir directs T4 passengers to a free inter-terminal train, Underground or H30 bus connection.
Return journey: For Heathrow to Reading, board RA1 outside arrivals at T2 stops 11–12, T3 stops 7–8 or T5 stop 9. Check the final departure from your terminal before flying; a late landing can leave a rail or licensed-car journey as the remaining option.

Route intelligence
What matters on this journey
The specific costs, transport links and timing that affect a Reading to Heathrow Airport journey.
Traffic and timing
The direct road route follows the M4 east from Reading, with the main delay risk around Junction 4B for the M25 and the airport spur. A clear run can take about 35 minutes, but commuter traffic, freight and incidents can push it towards an hour.
Train, coach and interchange friction
RA1 leaves from outside Reading station and runs directly to Heathrow Terminals 2, 3 and 5, with departures advertised up to every 20 minutes. The rail alternative changes at Hayes & Harlington, which removes some road risk but adds an interchange with luggage.
Door-to-door fit
A car becomes more useful when the pickup is well away from Reading station, the flight falls outside the useful coach times, or several passengers are splitting one vehicle fare. Compare the complete live price with the per-person coach or rail total.
Final checks
Check the flight terminal before booking. RA1 does not serve Terminal 4 directly. If driving, Heathrow charges £7 for each terminal drop-off entry, requires payment by midnight the next day and does not allow waiting or pick-ups on the forecourt.
Booking checklist
Make the route decision properly
What is the best public transport from Reading to Heathrow?
For most journeys, the RA1 coach is simpler because it runs from Reading station directly to Terminals 2, 3 and 5. The train can be useful when M4 traffic is severe, but it requires a change at Hayes & Harlington and you must board the correct Heathrow branch.
How much is RailAir from Reading to Heathrow?
RailAir advertised online fares from £24 when checked on 27 August 2026. Treat that as a starting fare, not a guaranteed price for every departure. Check the live booking result for your date, passenger mix and ticket type.
Where do I catch RailAir at Reading station?
The coach stops outside Reading station by the exit nearest M&S Simply Food. RailAir customers can use the nearby lounge. Follow the RailAir signs from the platforms rather than heading to the town-centre bus stops.
How do I travel from Reading to Heathrow Terminal 2 or 3?
Take the direct RA1 from Reading station. At Heathrow it serves Terminal 2 at bus stops 11–12 and Terminal 3 at bus stops 7–8, outside arrivals. Confirm the stop sequence and live arrival time on the RA1 timetable.
How do I travel from Reading to Heathrow Terminal 4?
RA1 does not stop at Terminal 4. Travel to Terminal 2, 3 or 5, then use Heathrow's free inter-terminal trains, Underground or H30 bus. Oyster or contactless opens the rail and Underground gates without charging; RailAir also says free train-transfer tickets are available at the stations.
How do I travel from Reading to Heathrow Terminal 5?
RA1 runs directly from Reading station to Terminal 5 and uses bus stop 9. This avoids the Hayes & Harlington rail change. Allow extra time when the M4 is congested and check the live timetable before leaving.
Is there a direct train from Reading to Heathrow?
No. Reading and Heathrow are both on the Elizabeth line map, but they sit on different branches. Travel east from Reading to Hayes & Harlington, then change for a Heathrow-bound train and check whether it continues to Terminal 4 or Terminal 5.
Is RailAir faster than the train from Reading to Heathrow?
RailAir advertises the direct coach from about 40 minutes. Heathrow describes the rail journey via Hayes & Harlington as around one hour. Road congestion can reverse that advantage, so compare the live coach and rail times on the day.
Can I take large suitcases on RailAir?
RailAir coaches have dedicated luggage space, which avoids carrying cases through the change at Hayes & Harlington. The train remains possible with luggage, but the interchange and commuter crowding can make it less comfortable.
Does RailAir run from Reading every day?
RailAir says the RA1 service operates seven days a week and advertises departures up to every 20 minutes. Frequencies change across the day and special timetables can apply, so check the dated timetable rather than relying on the headline frequency.
What should I check when driving from Reading to Heathrow?
Confirm the terminal before joining the M4 and allow for congestion around the M4/M25 interchange. Heathrow charges £7 each time a vehicle enters a terminal drop-off area. Pay by midnight the next day; the forecourt allows set-down only, with no waiting or pick-up.
