London Heathrow Airport is one of the busiest and most iconic international airports in the world, serving as a major hub for business travellers, tourists, and international visitors alike. If you’re planning a journey to or from Heathrow, understanding its runway system and operations can give you a deeper appreciation for its capacity and efficiency.
At Orange Airport Transfer, we aim to make your airport journey smooth, timely, and comfortable. In this post, we answer a common question: How many runways does Heathrow Airport have?
An Overview of Heathrow Airport
Located approximately 20 miles (32 km) west of Central London, Heathrow Airport (IATA: LHR) is the United Kingdom’s largest and busiest airport. It handled over 83.9 million passengers in 2024 and connects London with over 180 destinations worldwide.
The airport comprises five terminals (Terminals 1–5), with Terminals 2, 3, 4, and 5 currently in operation. Terminal 1 has been closed since 2015. Despite its size and passenger volume, Heathrow operates with a limited number of runways something many travellers find surprising.
How Many Runways Does Heathrow Airport Have?
Heathrow Airport currently has two runways.
These runways are:
- Runway 09L/27R (North Runway)
- Runway 09R/27L (South Runway)
These two parallel runways are aligned east–west and are spaced 1,400 metres (4,593 feet) apart. Each runway is approximately 3,900 metres (12,800 feet) long and is capable of handling the world’s largest aircraft, including the Airbus A380.
How the Runways Operate
To maximise efficiency and minimise noise for surrounding communities, Heathrow operates a “runway alternation” system. Here’s how it works:
- During westerly operations (the most common due to prevailing winds), one runway is used for arrivals and the other for departures. Halfway through the day, the roles of the runways are switched.
- During easterly operations, a similar arrangement is followed but less frequently due to wind conditions.
This system allows nearby residents periodic relief from aircraft noise and helps manage traffic flow during busy periods.
Why Only Two Runways for a Major International Hub?
For an airport of Heathrow’s global stature, having only two runways may seem unusual. Here’s why:
- Historical Planning Restrictions: Heathrow was built in the 1940s when air traffic was significantly lighter. Expansion over time has been limited due to noise concerns and surrounding urban development.
- High Efficiency: Despite having just two runways, Heathrow uses advanced air traffic control technology and scheduling systems, allowing it to handle more flights per runway than many other international airports.
- Environmental and Community Concerns: Expansion plans have always met resistance from environmental groups and local residents concerned about pollution and noise levels.
Is a Third Runway Coming to Heathrow?
Yes, but with complications.
The proposal for a third runway at Heathrow Airport has been in discussion for years. The aim is to increase capacity, reduce delays, and boost the UK’s global connectivity.
- In 2018, the UK Parliament approved the third runway plan.
- However, in 2020, the Court of Appeal ruled it unlawful due to climate change concerns.
- The Supreme Court later overturned this ruling in late 2020, allowing the project to move forward.
- As of 2024, the project remains under planning and environmental scrutiny, and construction has not yet begun.
When completed, the third runway would provide significant relief and future-proof Heathrow for decades to come.
Why Runway Information Matters to Travellers
Understanding the runway setup is more than just aviation trivia—it can directly impact your travel experience:
- Delays: Heathrow’s limited runway capacity means it operates close to its limit most of the day. Weather issues or technical problems can easily cause delays.
- Noise-sensitive Scheduling: If you’re staying near the airport, knowing about runway alternation might help you choose a quieter hotel location.
- Taxi Services and Timing: During peak periods, runways operate at near-full capacity. This can mean long queues for takeoff or landing, so it’s crucial to book your taxi to Heathrow Airport with buffer time.
