Heathrow Airport

Heathrow is a very big airport.

It is in London. It is the largest airport in that area.

It started as a small airfield. It grew much larger after a big war. Now it has two long runways.

Many planes fly to many lands. They carry people and goods. Some planes carry books and fish.

There are four big buildings for people. One building is just for cargo. This helps move things around the world.

It is a very busy place for travel.

Heathrow Airport is a very busy place in London.

It is the largest airport in the London area. It began as a small airfield in 1930. It grew much larger after World War II.

Long ago, the airport had six runways. Today, it has two long runways that run side by side.

Many planes use Heathrow to travel. Over 89 airlines fly to 214 different places. In 2024, 83.9 million people traveled through the airport.

Some planes carry people in four large terminals. Other planes carry cargo, which means goods like books or fish.

Noise is a big deal at Heathrow. The airport tries to help people living nearby. During the day, planes often take off to the west. This helps keep the noise away from many houses. At night, there are strict rules. The loudest planes are not allowed to fly at certain times.

This helps keep the area quieter while people sleep.

Heathrow Airport is a massive hub for travelers in England.

It is the largest international airport serving London. Many people call it the primary airport for the United Kingdom. It is the biggest of six international airports in the London system. In 2024, it had the most international connections in the world. By 2025, it was the busiest airport in all of Europe.

It is also the fifth-busiest airport in the world for passengers.

Moving planes through the sky is a careful process. First, planes fly to one of four holding points. These are like waiting rooms in the sky. Air traffic controllers in Swanwick guide the planes to their final approach. They merge the planes into a single stream of traffic. Sometimes, the planes fly very close to each other. To help the environment, planes often use a continuous descent approach. This helps them glide down more smoothly.

Heathrow has a long and changing history.

It started as a small airfield back in 1930. The airport opened officially on 25 March 1946. At that time, it was simply called London Airport. It was renamed Heathrow Airport in September 1966. This change helped avoid confusion with Gatwick and Stansted airports. After World War II, the site grew much larger. In the 1950s, the airport actually had six different runways. Today, it uses two parallel east-west runways instead.

There are many important numbers to know about this place.

Over 89 different airlines use the airport every day. They fly to 214 destinations in 84 different countries. In 2021, 19.4 million people used the airport. The busiest year on record was 2024 with 83.9 million passengers. The airport also moves a lot of cargo. In 2022, it handled 1.4 million tonnes of goods. Some of these items include books, salmon, and medicine.

Everything at the airport is built to help people and planes.

There are four passenger terminals numbered 2 through 5. There is also a special terminal just for cargo. To help travelers feel at home, there are many chapels. You can find rooms for many different faiths there. The airport even has a resident press corps. This group includes six photographers and one TV crew. They work to report news to the whole world.

Heathrow Airport is the primary international gateway for London and the United Kingdom.

It stands as the largest of six international airports within the London airport system. While other airports like Gatwick and Stansted serve the region, Heathrow remains the most significant hub. In 2025, it was recognized as the busiest airport in Europe. It also held the title of the fifth-busiest airport globally by passenger traffic. Furthermore, it ranked as the second-busiest airport in the world for international passenger traffic. In 2024, Heathrow recorded the highest number of international connections of any airport on Earth.

Managing the movement of aircraft requires a highly organized sequence of steps. Inbound aircraft typically follow Standard Arrival Routes, known as STARs. These routes lead to four specific VOR installations. These installations define four "stacks," which act as aerial waiting areas for planes. Air traffic controllers at Approach Control in Swanwick, Hampshire, manage these aircraft. They merge the planes from the four holding stacks into a single, orderly stream of traffic. To reduce environmental impacts, controllers often use continuous descent approach techniques. Once a plane is on its final approach, control is transferred to the Heathrow Tower.

The physical layout of the airport has evolved significantly over several decades.

In the 1950s, the airport featured six runways arranged in a hexagram shape. These three pairs of runways were set at different angles. Two runways were always positioned within 30 degrees of the wind direction. Today, the airport has transitioned to two parallel east-west runways. These modern runways are extended versions of the original east-west paths. Interestingly, much of the old runway system is still visible from the air. These former runways have been incorporated into the current taxiway system.

Heathrow is a massive operation serving a diverse global network.

The airport is used by more than 89 different airlines. These carriers fly to 214 destinations across 84 countries. In 2021, the airport served 19.4 million passengers. This included 17 million international travelers and 2.4 million domestic passengers. The most successful year in its history was 2024, with 83.9 million passengers. One of the busiest routes connects Heathrow to New York's JFK Airport. In 2021, over three million people traveled between these two specific locations.

The airport is organized into several distinct functional areas.

There are four operational passenger terminals, numbered 2 through 5. In addition to these, there is one dedicated cargo terminal. The cargo operations are quite large, handling 1.4 million tonnes of goods in 2022. Common exports include books, salmon, and medicine, with major destinations being the United States, China, and the United Arab Emirates. The airport also serves as the primary hub for British Airways and Virgin Atlantic. This infrastructure supports a massive flow of both people and commercial goods.

Noise management is a critical part of Heathrow's daily operations.

To minimize noise for residents, the airport uses runway alternation. During westerly operations, aircraft take off to the west and land from the east. This helps avoid flying directly over the most densely populated areas. The airport also swaps the use of runways 27R and 27L at 15:00 local time daily. Night-time flights are strictly regulated between 23:00 and 04:00. During this period, the noisiest aircraft types are not allowed to operate. A Quota Count system also limits the total amount of noise permitted at night.

Heathrow has a long history of growth and regulatory change.

It began as a small airfield in 1930. It officially opened as London Airport on 25 March 1946. The name was changed to Heathrow Airport in September 1966 to avoid confusion with Gatwick and Stansted. The Central Terminal Area was designed by Sir Frederick Gibberd. Over time, the Civil Aviation Authority has regulated the fees airlines pay to land. Additionally, the allocation of landing slots is managed by Airport Co-ordination Limited. These rules ensure the airport functions efficiently within the global aviation system.
