Reading & Thames Valley to Heathrow
The Thames Valley corridor from Reading through Maidenhead and Slough to Heathrow is one of the busiest airport transfer routes in the country. The M4 motorway provides a direct connection, and several public transport options are available.
RailAir Coach (Reading only)
The RailAir coach runs between Reading station and all Heathrow terminals.
- Journey time: 45-70 minutes
- Frequency: Every 20-30 minutes
- Cost: £18-25 single
- Pros: Direct, dedicated airport service, departs from Reading station
- Cons: Fixed schedule, stuck in M4 traffic, does not pick up from home, luggage handling at Reading station
Elizabeth Line
The Elizabeth Line connects Reading, Twyford, Maidenhead, Taplow, Burnham, Slough, Langley, Iver, and West Drayton with Heathrow Terminals 2/3.
- Journey time: 25-55 minutes depending on station
- Cost: £5-12 (Oyster/contactless)
- Pros: Modern, affordable, frequent, direct from many Thames Valley stations
- Cons: Some services require a change, luggage on busy trains, no direct service to T5 from all stations, does not run 24/7 (first trains ~5:30am)
Taxi Transfer
| From | Distance | Taxi Time |
|---|---|---|
| Slough | 5 miles | 10-20 mins |
| Maidenhead | 13 miles | 20-35 mins |
| Windsor | 8 miles | 15-25 mins |
| Reading | 30 miles | 35-55 mins |
| Henley-on-Thames | 25 miles | 35-50 mins |

A taxi is faster than the RailAir from Reading (35-45 minutes vs 45-70 minutes), picks you up from your door, and drops you at the terminal forecourt. For two or more travellers, the cost is comparable to RailAir tickets.
Driving and Parking
The M4 makes driving from Reading to Heathrow easy — it is a straight motorway run. But parking at Heathrow is expensive. Long Stay parking costs £60-100 per week, plus fuel and wear on your car.
