Quick Answer
The best overall way to get from Reading to Heathrow Airport is the train via London Paddington — take a Great Western Railway (GWR) service to Paddington (≈ 25 min), then the Heathrow Express to Terminals 2&3 (≈ 15 min). Total time: 45–55 minutes; cost: £35–£55 (≈ $44–$70) depending on advance booking. For a balance of cost and simplicity, the RailAir express bus (direct, no changes) takes about 60–75 minutes and costs £24 (≈ $30). The cheapest option is also the RailAir bus; the fastest is the train + Heathrow Express combination.
Train & Rail Connections from Reading to Heathrow
Reading is a major rail hub, served by Great Western Railway (GWR) and CrossCountry services. While there is no direct train from Reading to Heathrow Airport, the connection via London Paddington is fast, frequent, and reliable. Below we break down the two main rail routes, with a comparison table to help you choose.
Route 1: Via London Paddington (Recommended – Fastest)
- Step 1: GWR from Reading to London Paddington — every 10–15 minutes, journey time 22–30 minutes.
- Step 2: Transfer at Paddington to the Heathrow Express (non-stop to Terminals 2&3 in 15 minutes) or the Elizabeth line (stops at all terminals, 30 minutes).
- Total time: 45–55 minutes (Heathrow Express) or 55–70 minutes (Elizabeth line).
- Cost: From £35–£55 (≈ $44–$70) for a standard open return; advance tickets can be as low as £25 (≈ $32).
Route 2: Via Hayes & Harlington (Budget – Slower)
- Step 1: GWR or local train from Reading to Hayes & Harlington (≈ 35–45 minutes).
- Step 2: Change to the Elizabeth line westbound to Heathrow (≈ 15–20 minutes).
- Total time: 55–70 minutes depending on connection.
- Cost: From £18–£28 (≈ $23–$36) off-peak, making it the cheapest rail option.
Train Comparison Table
| Route | Operator | Time | Cost (one-way) | Changes | Best For |
|---|---|---|---|---|---|
| Reading → Paddington → Heathrow Express | GWR + Heathrow Express | 45–55 min | £35–£55 (≈ $44–$70) | 1 change (Paddington) | Speed, convenience, business travelers |
| Reading → Paddington → Elizabeth line | GWR + Elizabeth line | 55–70 min | £28–£40 (≈ $36–$51) | 1 change (Paddington) | Balance of cost and speed |
| Reading → Hayes & Harlington → Elizabeth line | GWR + Elizabeth line | 55–70 min | £18–£28 (≈ $23–$36) | 1 change (Hayes) | Budget rail, off-peak travel |
Train tip: Book advance tickets via GWR or Trainline for the best fares. The Heathrow Express allows free Wi-Fi and has ample luggage space. If you are using a Railcard, you can save 1/3 on most GWR and Elizabeth line fares (but not on Heathrow Express).
Flight from Reading to Heathrow? (What You Need to Know)
Flying from Reading to Heathrow is not a practical option — there are no direct commercial flights between Reading and Heathrow. However, some travelers consider flying from London Heathrow (LHR) itself, which is the destination. The only "flight" scenario would be if you are connecting from a long-haul flight at Heathrow and need to reach Reading — but that is the reverse route.
Important comparison: The total door-to-door time for the train journey (Reading station to Heathrow terminal) is 45–70 minutes. The fastest flight from a regional airport like Southampton or Bristol to Heathrow would involve check-in, security, and transit time, making it 3–4 hours — significantly slower. For distances under 100 km (62 miles), rail is always the superior choice.
Verdict: Do not consider flying. The train or bus is faster, cheaper, and more reliable. If you are arriving at Heathrow and need to get to Reading, follow the same routes in reverse — the RailAir bus and GWR trains are the best options.
Bus & Coach Services: The Budget Champion
The RailAir express bus (operated by Reading Buses) is the most popular direct coach service between Reading and Heathrow. It runs 24/7 and departs from Reading Station’s south side (Stop SA). No changes, no hassle.
RailAir Coach Details
- Route: Reading Station → Heathrow Terminals 1–5 (stops at all terminals).
- Frequency: Every 20–30 minutes during the day, hourly overnight.
- Journey time: 60–75 minutes (depending on traffic and terminal).
- Cost: £24 (≈ $30) one-way; £42 (≈ $53) return. Children under 16 travel for £12 (≈ $15).
- Luggage: Up to 2 medium suitcases (20 kg each) + 1 hand luggage.
Night Bus vs. Day Bus
The RailAir service operates 24 hours, making it a reliable choice for early morning flights (before 06:00) or late arrivals. The night service runs hourly (00:00–05:00) and takes roughly the same time. There is no separate "night bus" — it is the same RailAir route, just with reduced frequency.
Other Coach Options
National Express also runs a limited service from Reading to Heathrow (route 022), but it is less frequent and often more expensive (£28–£35, ≈ $36–$44). The RailAir bus is generally the better choice for price and reliability.
Bus tip: Book online at Reading Buses RailAir to guarantee your seat, especially during peak holiday periods. The coach has free Wi-Fi and USB charging ports.
| Operator | Time | Cost (one-way) | Frequency | Best For |
|---|---|---|---|---|
| RailAir (Reading Buses) | 60–75 min | £24 (≈ $30) | Every 20–30 min (day), hourly (night) | Budget, direct, 24/7 availability |
| National Express (route 022) | 65–80 min | £28–£35 (≈ $36–$44) | Every 2–3 hours | If RailAir is sold out |
Taxi & Private Transfer: Premium Convenience
A private taxi or minicab from Reading to Heathrow is the most convenient door-to-door option, but it comes at a premium. Fares typically range from £75 to £110 (≈ $95–$140) depending on the provider, vehicle type, and time of day.
When to Choose a Taxi
- Late night / early morning (before 05:00) when trains and buses are less frequent.
- Large groups (4+ people) — a taxi can be cost-effective split between passengers.
- Heavy or bulky luggage (e.g., golf clubs, skis, multiple large suitcases).
- Reduced mobility or special assistance needs.
- Business travelers who value time and comfort.
Price Range by Provider Type
| Provider Type | Typical Fare (Reading → Heathrow) | Booking Required? | Notes |

| Private Minicab (pre-booked) | £75–£100 (≈ $95–$127) | Yes — at least 2 hours ahead | Fixed price, often cheaper than black cab |
| Uber | £65–£90 (≈ $83–$114) | Via app | Price varies with demand; not always available at peak |
| Executive / Luxury car | £110–£160 (≈ $140–$203) | Yes — 24h+ recommended | Includes meet-and-greet, bottled water, etc. |
Important: Always pre-book a private taxi if you need a fixed price and guaranteed pickup. Use reputable firms such as Greenwich Cars or Addison Lee. Avoid unlicensed cabs at the station.

Traveler Tips & Practical Insights
Based on frequent traveler feedback and local knowledge, here are essential tips to make your journey from Reading to Heathrow smoother.
1. Luggage – Use Takkyubin (Luggage Forwarding)
If you have heavy luggage, consider using Takkyubin (luggage delivery service) from Reading to Heathrow. Companies like Luggage Forward or Send My Bag can collect your bags from your hotel in Reading and deliver them to your Heathrow terminal. This frees you up to travel light on the train or bus. Cost: around £30–£50 (≈ $38–$64) per bag.
2. Paddington Station – Allow Extra Time for Connections
Paddington is a large station. If you are taking the Heathrow Express, the platform is separate from the main GWR platforms. Allow 10–15 minutes to walk from the GWR arrival platform to the Heathrow Express departure gate (especially if you have luggage). Follow the purple Heathrow Express signs.
3. Avoid Peak Hours for Cheaper Fares
If you can travel between 10:00 and 15:00 or after 19:00, train fares are significantly cheaper. Off-peak returns on GWR can be half the price of peak-time tickets. The RailAir bus fares are the same at all times.
4. Booking in Advance – Especially for Holidays
During Christmas, Easter, and summer holidays, trains and buses can sell out. Book at least 2–3 weeks ahead for the best train advance fares. The RailAir bus rarely sells out, but it's still wise to book online.
5. Check Your Terminal – Heathrow Has 5 Terminals
Heathrow Terminals 2&3, 4, and 5 are served differently. The Heathrow Express stops at Terminals 2&3 and 5 only. The Elizabeth line and RailAir bus stop at all terminals. If you are departing from Terminal 4, you will need to take the Elizabeth line or a shuttle bus — the Heathrow Express does not serve Terminal 4.
