London Heathrow Airport

Two runways, around 84 million passengers a year and widebodies a few minutes apart: for spotters, London Heathrow is something like Europe’s Champions League. On a single afternoon more Airbus A380s, Boeing 777s and 787s land here than at most German airports in a week. The catch: there’s no comfortable observation deck, and which spot works at any moment is decided by the wind and a fixed runway switch. If you understand both, Heathrow gives you one of the most impressive spotting days Europe has to offer.

From a field airfield to Europe’s biggest hub

Heathrow lies about 23 kilometers west of central London, on flat land between the boroughs of Hillingdon and Hounslow. The airport takes its name from a small hamlet called Heath Row, which had to make way for the airfield. Civil flights have operated here since March 25, 1946 – at first under the name London Airport; only since 1966 has the site been officially called Heathrow.

In the decades that followed, the airport grew mainly toward the middle. The central terminal area between the two runways gradually got new buildings, including the Oceanic Terminal for long-haul traffic in 1961, today’s Terminal 3. Terminal 4 followed in the south in 1986, the huge Terminal 5 in the west for British Airways in 2008 and the new Terminal 2 in 2014. The old Terminal 1 closed in 2015.

Two runways at the limit

The astonishing thing about Heathrow isn’t its size but how cramped it is. All traffic runs over just two parallel runways in an east-west direction. The north runway 09L/27R is 3,902 meters long, the south runway 09R/27L 3,660 meters. About 480,000 flight movements a year are allowed – and the airport uses up that limit practically in full. In 2024 there were just under 474,000 takeoffs and landings.

For you as a spotter that has a pleasant consequence: there’s hardly any downtime. At peak times one landing follows the next, often separated only by the required spacing because of wake turbulence. Why heavy widebodies need more space between aircraft is explained in the article on wake turbulence separation. What the numbers in the runway designations mean is covered in the article Runway designations at airports.

Runway switch: the most important appointment of the day

Because Heathrow lies in the middle of a densely populated area, the airport spreads the noise according to fixed rules. In westerly operations – aircraft then land coming from the east heading west – Heathrow uses one runway for landings and the other for takeoffs. At 3 pm the two swap roles. Between 6 and 7 am, the busiest arrival hour, both runways may be used for landings.

On top of that comes a weekly rhythm: if 27L takes the landings until 3 pm this week, next week it only becomes the landing runway from 3 pm. Heathrow publishes the switch schedule on its own website. For your planning that’s gold, because the classic among the spots – Myrtle Avenue under the approach to 27L – only works when landings are happening there.

In easterly operations everything looks different. The aircraft then land coming from the west heading east, and the 3 pm switch doesn’t apply during the day. According to Heathrow, changes to the infrastructure are still needed for that. Another peculiarity goes back to the former Cranford Agreement: no takeoffs toward the east from the north runway. How you can estimate wind and runway direction at home is explained in the article Understanding the runway direction in use at an airport; the right tool is a look at the METAR for EGLL.

British Airways and Terminal 5

Heathrow is the home hub of British Airways – and you see that on every runway. BA operates most of its long-haul fleet from here, from the Airbus A380 and the A350-1000 to the Boeing 787-10, 787-9 and the 777 variants such as the 777-200ER and 777-300ER. On short-haul, A320 family types dominate, including the A320neo and the A321neo.

Terminal 5 at the west end of the grounds was built specially for British Airways and opened in 2008. It consists of a main building and satellites, where BA’s A380 is handled as well. Besides BA, Iberia is handled there too – both belong to the International Airlines Group. Heathrow is also the base of Virgin Atlantic, whose long-haul fleet includes the A350-1000, A330-900 and 787-9 and which flies from Terminal 3.

Who else lands at Heathrow

Heathrow’s real strength is variety. Around 90 airlines connect Heathrow with a good 200 destinations. The terminals are sorted roughly by alliance, which helps you read what’s going on on the ground:

The assignment isn’t rigid, every terminal has exceptions, and airlines occasionally move. For you at the fence it hardly matters anyway – on approach everything comes in over the same two runways. What’s exciting are the guests from Asia, Africa and South America that you rarely get to see at German airports. Many of them wear eye-catching paint schemes; tips on how to find special liveries are in the article Finding special liveries. How the three alliances fit together is explained in Star Alliance, oneworld and SkyTeam.

Spotting without a deck: the spots around the airport

If you’re spoiled by German airports with visitors’ hills and observation decks, you have to rethink at Heathrow. There’s no classic observation deck in the terminal. Spotting happens from public areas around the grounds – and that works surprisingly well because the approaches run over residential areas.

The best-known place is Myrtle Avenue in the Hatton district at the southeast corner. At the end of a residential street there’s a meadow directly under the final approach to 27L. The aircraft come in so low here that a standard zoom is often enough. The nearest Tube station is Hatton Cross on the Piccadilly line, about a ten-minute walk away. Everything on light, focal length and time windows is in the spot guide to Myrtle Avenue at London Heathrow Airport.

When the north runway is landing, you move to the north side. A covered viewing stand on Newall Road and hotels on Bath Road with rooms facing the airfield are well known there. In easterly operations the departures from 09R, which climb out over Hatton, are worth a visit – harder to photograph, but loud and impressive.

Light and equipment

Both runways run east-west, and the sun is in the south at midday. From the south side – that is, from Hatton and Myrtle Avenue – you have the sun behind you or to the side behind you during the day. The afternoon in particular brings beautiful light, when the sun falls from the southwest on the approaching aircraft. On the north side, by contrast, you tend to shoot into the sun; early mornings in summer or overcast days are worth it there. You can plan the exact sun position with the article Planning the sun position at your photo spot – or directly with the sun position planner in Planetrack.

At the approach spots you need less focal length than you might think. At Myrtle Avenue a telephoto zoom up to 200 mm covers almost everything, and for widebodies directly overhead often even a standard zoom does. On the north side, with more distance to the runway, more telephoto helps. Which lenses suit what is covered in the article Which focal length for plane spotting?. English weather changes quickly – a rain cover for your camera belongs in your bag.

Quiet hours and the daily rhythm

Heathrow has a strict night regulation. The night quota period lasts from 11:30 pm to 6:00 am; during this time a limited quota of flights applies, and every movement counts against a points account depending on the aircraft’s noise class. The loudest noise classes are excluded entirely during the night hours. In addition, a voluntary commitment applies that no scheduled arrivals land before 4:30 am.

For spotters that means the day starts early. From 4:30 am the first scheduled arrivals may land, mostly overnight long-haul flights; in the hour between 6 and 7 am landings happen on both runways. After that, operations run into the late evening without a real break. In the morning many flights from North America arrive after crossing the Atlantic overnight – a good time for widebodies of US airlines such as Delta, United and American. Exact times change with every schedule.

Cargo, expansion and the third runway

Heathrow is also the UK’s most important cargo airport. In 2024 a good 1.5 million tonnes were handled, the vast majority of it in the bellies of passenger aircraft. Pure freighters are therefore rarer here than at cargo hubs such as Leipzig/Halle.

A third runway has been argued over for decades. After several attempts, court cases and political U-turns, the British government backed the expansion in January 2025 and in November selected the airport’s design: a runway up to 3,500 meters long in the northwest, for which the M25 motorway, among other things, has to be rerouted. The project isn’t approved yet. According to media reports from September 2026, government circles expect approval by 2029; opening is only considered realistic toward the end of the 2030s. Until then it stays at two runways – and at the tight rhythm that makes Heathrow so rewarding for spotters.

Heathrow compared

Among Europe’s big hubs, Heathrow is the one with the fewest runways and the densest long-haul traffic. Amsterdam Schiphol Airport and Paris Charles de Gaulle Airport have more runways and therefore more room to maneuver, and Frankfurt Airport offers a fixed spot at the runway end with Zeppelinheim. If you’re looking for spotting places with infrastructure, you’ll find more comfort at the Polderbaan in Schiphol or at the Runway Visitor Park in Manchester.

And if you’re into British aviation history, the article on the history of Concorde tells the story of the supersonic jet that flew from Heathrow to New York until 2003.

Conclusion

London Heathrow isn’t a comfortable airport for spotters, but one of the most rewarding. Two runways at the limit, a British Airways hub with A380s, A350s and 787s and long-haul service from all over the world mean you hardly experience a minute without movement. Instead of a deck there are public approach spots, above all Myrtle Avenue, which is easy to reach by Tube.

Planning and timing make the difference: the switch schedule, wind and light decide whether you’re standing at the right runway at the right time. If you sort that out beforehand, you come back from Heathrow with a memory card full of widebodies.
