London Heathrow Airport is one of the busiest airports in the entire world. It handles tens of millions of passengers every single year and connects the UK to hundreds of destinations across every continent. But here is the thing that trips up so many travellers the moment they arrive: Heathrow does not have just one terminal. It has four. And they are not all in the same place.
Getting to the wrong terminal wastes time. It causes stress. In some cases, it means missing your flight. That is exactly why having a solid Heathrow airport terminal guide before you travel makes such a big difference.
This article breaks down everything you need to know. Which terminal is for which airline, what each terminal looks like inside, how to get between them, how to get to and from London, and all the practical tips that make your time at Heathrow much easier.
Let us get into it.
How Many Terminals Does Heathrow Have?
Heathrow currently has four active passenger terminals. They are numbered Terminal 2, Terminal 3, Terminal 4, and Terminal 5. There is no Terminal 1 in operation. It was closed back in 2015 and was eventually demolished to make way for the expansion of Terminal 2.
Each terminal is a separate building with its own check-in hall, security, departures lounge, shops, restaurants, and arrivals area. This is very different from airports like Birmingham, which operate from a single building. At Heathrow, where you need to be depends entirely on which airline you are flying with.
The terminals are spread across a large site on the western edge of London, near Hounslow. Terminals 2 and 3 sit close together in the central part of the airport. Terminal 4 is to the south. Terminal 5 is to the west. Getting from one to another takes time, which is why knowing your terminal before you even leave home is so important.
Terminal 2: The Queen’s Terminal
Terminal 2 is the newest terminal at Heathrow. It reopened in June 2014 after a complete rebuild and was officially named The Queen’s Terminal in honour of Queen Elizabeth II. It is a spacious, modern building with a bright open feel. Many passengers consider it the most pleasant terminal at Heathrow to pass through.
Which Airlines Use Terminal 2?
Terminal 2 is the main base for Star Alliance member airlines at Heathrow. The Star Alliance is one of the three major global airline groups, and it includes some very well-known carriers.
Key airlines at Terminal 2 include United Airlines, Lufthansa, Air Canada, Singapore Airlines, Turkish Airlines, Swiss International Air Lines, TAP Air Portugal, Scandinavian Airlines (SAS), All Nippon Airways (ANA), and South African Airways. Aer Lingus and Eurowings also operate from here.
If you are flying with a Star Alliance carrier, Terminal 2 is almost certainly where you need to be. But always double-check on your boarding pass or booking confirmation first.
What Is Inside Terminal 2?
The check-in area is on Level 5 and is divided into zones labelled A through D. Once you have dropped your bags, you head through security which is also on Level 5. After clearing security you reach the departure lounge, which has a good range of shops and places to eat.
Dining options include Heston Blumenthal’s Perfectionists’ Café, a Pret a Manger, a Caffè Nero, and the popular London Pride pub. Shopping covers everything from Duty Free and WHSmith to Hamleys, Burberry, and Fortnum and Mason. The facilities are genuinely good.
Terminal 3: Long-Haul and Oneworld Airlines
Terminal 3 has been part of Heathrow since the 1960s and has gone through multiple refurbishments since then. It handles mostly long-haul international routes. It is one of the busiest terminals at the airport and is home to some of the world’s most famous airlines.
Which Airlines Use Terminal 3?
Terminal 3 is a mix of Oneworld alliance carriers and several independent long-haul airlines. Key names here include Virgin Atlantic, Emirates, American Airlines, Qantas, Cathay Pacific, Japan Airlines, Finnair, and Air France. Delta Air Lines and KLM also operate some services from Terminal 3.
Emirates deserves a special mention. The airline operates multiple daily flights between Heathrow and Dubai, many of them on the Airbus A380, and Terminal 3 is their London base. If you are flying Emirates, this is where you go.
What Is Inside Terminal 3?
Terminal 3 is large but well-signposted. Your airline determines which zone you use for check-in, either Zone A or Zone B. After check-in, you move through to security, and queues here can run longer than at other terminals, so give yourself plenty of time before your flight.
The departure lounge has an excellent selection of restaurants, including Wagamama, Gordon Ramsay’s plane food, and a variety of bars and cafés. Shopping ranges from standard newsagents and pharmacy outlets to designer brands and Duty Free.
Terminal 3 is also home to some outstanding airport lounges. The Virgin Atlantic Clubhouse is widely regarded as one of the best airport lounges in the world. It offers restaurant-quality food, a bar, beauty treatments, and a truly relaxed atmosphere. The Qantas London Lounge and Cathay Pacific Lounges are also excellent options here.
Terminal 4: SkyTeam and Gulf Carriers
Terminal 4 sits on the southern side of the airport, separated from the other three terminals by the runway. It was opened back in 1986 and originally served British Airways before they moved to Terminal 5 in 2008. Today it primarily serves SkyTeam airlines and a number of Gulf and Asian carriers.
Which Airlines Use Terminal 4?
Airlines at Terminal 4 include KLM, Air France, Korean Air, China Eastern, Vietnam Airlines, Saudia, Kenya Airways, TAROM, and ITA Airways. Several Gulf and African carriers also operate from here.
It is worth noting that some SkyTeam airlines operate from Terminal 3 instead of Terminal 4. This includes Delta Air Lines. So always check your specific booking before assuming which terminal to head for.
What Is Inside Terminal 4?
Terminal 4 tends to be less crowded than Terminal 2 or Terminal 3. The security queues are often shorter and the atmosphere is slightly calmer. This is appreciated by many travellers, especially on long-haul journeys when you just want a bit of peace.
Travellers enjoy comfortable lounge options here, including the Qatar Airways Premium Lounge and the Etihad Airways Lounge, and both receive consistently strong reviews. Dining and shopping offer fewer choices than Terminals 2 and 3, but the terminal covers all the basics well. There are cafes, a restaurant, a bar, and a duty-free shop.
Because Terminal 4 is physically separated from the other terminals, you cannot walk between it and Terminals 2 or 3. You need to take a shuttle train or the Underground.
Terminal 5: British Airways Exclusive Hub
Terminal 5 is the largest and most impressive terminal building at Heathrow. It opened in March 2008 and is exclusively used by British Airways. It is also one of the largest free-standing buildings in the entire United Kingdom. The scale of it is genuinely remarkable when you walk in for the first time.
Which Airlines Use Terminal 5?
British Airways is the only airline based at Terminal 5. This includes both their short-haul European routes and their long-haul flights to North America, Asia, Africa, the Middle East, and beyond. Some British Airways flights also operate from Terminal 3, particularly where Terminal 5 is at capacity, so always check your specific booking.
Iberia, which is part of the same parent group as British Airways, previously operated from Terminal 5 but moved back to Terminal 3 in July 2022.
What Is Inside Terminal 5?
Terminal 5 is actually made up of three separate concourses: Concourse A, Concourse B, and Concourse C. Your gate will tell you which concourse you need. Concourse A is the main building where you check in and go through security. Concourses B and C are accessed via an underground people mover train. It takes about 10 minutes to reach the satellite buildings, so leave time for this.
The departure lounge in Terminal 5 is vast. There are dozens of shops and restaurants. The British Airways Galleries Club lounge and Concorde Room are here for premium passengers and elite members. Even if you are in economy, the food and shopping options are extensive.
Check-in at Terminal 5 closes 60 minutes before long-haul departures and 45 minutes before short-haul flights. Security must be cleared at least 35 minutes before your flight. Keep these times in mind.
Quick Airline to Terminal Reference
Here is a simple summary to help you find your terminal at a glance:
- Terminal 2 (Star Alliance): United Airlines, Lufthansa, Air Canada, Singapore Airlines, Turkish Airlines, Swiss, TAP, SAS, ANA, Aer Lingus
- Terminal 3 (Oneworld and Long-Haul): Virgin Atlantic, Emirates, American Airlines, Qantas, Cathay Pacific, Japan Airlines, Finnair, Delta, Air France (some routes), KLM (some routes)
- Terminal 4 (SkyTeam and Gulf): KLM, Air France, Korean Air, China Eastern, Vietnam Airlines, Saudia, Kenya Airways, ITA Airways
- Terminal 5 (British Airways Only): All British Airways flights (most), Iberia (check as some routes moved to T3)
This is a guide only. Always verify your exact terminal through your boarding pass, the airline app, or the official Heathrow website.
How to Find Out Which Terminal Your Flight Is In
The easiest way is to check your boarding pass or booking confirmation email. The terminal is usually printed or stated clearly. If not, you can visit the official Heathrow website at heathrow.com and use their terminal lookup tool. You simply enter your airline or flight number and it tells you which terminal to go to.
You can also check directly in your airline’s app. Most major airlines now show your terminal in the app alongside your boarding pass and gate information.
One important thing: airline terminal assignments do occasionally change. This happens especially when airlines move seasonal routes or adjust operations. Always confirm your terminal within 24 hours of your flight rather than relying on information you found weeks earlier.
Traveling Between Heathrow Terminals
Sometimes you need to change terminals. This might be because you are connecting to a second flight with a different airline, or because you were dropped at the wrong terminal. It happens.
Terminals 2 and 3 are connected by a landside walkway. This means you can walk between them without going through security again. The walk takes about 10 to 15 minutes at a comfortable pace.
Getting to Terminal 4 from Terminals 2 or 3 requires either the Elizabeth line, the Heathrow Express, or a free shuttle bus. The journey takes around 10 to 20 minutes. For Terminal 5 from the central terminals, the Elizabeth line or Heathrow Express also connects you. Again, roughly 15 to 20 minutes by rail.
There are free inter-terminal transfer tickets available at the train stations inside the airport. These are landside journeys so you would need to re-enter security at your new terminal. Always allow at least 90 minutes for inter-terminal connections, more if you are travelling during busy periods.
Heathrow Arrivals: What to Expect
When you land at Heathrow your first step is passport control. UK and Irish passport holders can use the eGates for automated processing. EU passport holders can also now use eGates in many circumstances. Other nationalities join the standard queue for a border force officer.
Passport control queues can be long during peak times. Afternoon arrivals when multiple long-haul flights land at similar times can see waits of 30 to 50 minutes in the main queue. This is normal at a busy international hub. It can feel frustrating but is just part of the process.
After passport control you collect your bags at the baggage reclaim carousels. Screens show which carousel your flight is assigned to. From there you pass through customs using either the green channel (nothing to declare) or the red channel (items to declare).
Each terminal has its own arrivals hall with information desks, ATMs, currency exchange, and a meeting point area. If someone is picking you up, this is where they wait.
Heathrow Departures: Getting Through Smoothly
Heathrow recommends arriving at least 3 hours before a long-haul flight and 2 hours before a short-haul flight. During school holiday periods and summer, add an extra 30 minutes on top of that.
Check-in can be done online before you arrive at the airport. Most airlines allow this from 24 hours before departure. After online check-in, head straight to the bag drop desk if you have hold luggage. Self-service bag drop is available for many airlines and is much faster than a staffed check-in desk.
Security is the part that takes the most time. At Heathrow you are required to place liquids in a clear resealable bag of no more than one litre total capacity. Each individual liquid must be in a container of 100ml or less. Laptops and large electronics are currently required to be removed from bags at most security lanes. Follow the instructions on the trays at the security belt carefully.
Fast track security passes are available at Heathrow and can be purchased in advance online. These take you through a dedicated lane and are worth considering if you are travelling during busy periods. Prices vary but typically start around £10 to £15 per person.
Getting To and From Heathrow
Heathrow Express
The Heathrow Express is the fastest way to travel between Heathrow and London Paddington. It takes 15 minutes from Terminal 5 and 21 minutes from Terminals 2 and 3. Terminal 4 passengers take a shuttle to the central station first. Trains run every 15 minutes.
Tickets cost more than other rail options but the speed is the big advantage. Booking in advance online gets you a cheaper fare. Walk-up prices at the ticket machine are significantly higher.
Elizabeth Line
The Elizabeth line (formerly known as Crossrail) offers a more affordable rail connection to London. It stops at Heathrow Terminals 2 and 3 (central), Terminal 4 on a separate spur, and Terminal 5 at its own station. The journey to central London takes around 40 to 50 minutes to Paddington or about an hour to the City and Canary Wharf.
The Elizabeth line is excellent value and runs frequently throughout the day. It also gives direct access to many more London stations than the Heathrow Express, making it the better option for most travellers.
London Underground (Piccadilly Line)
The Piccadilly line serves all Heathrow terminals and runs into central London. The journey to central London takes around 50 to 60 minutes from the airport. It is the cheapest rail option and runs frequently, including early mornings and late nights. It is not the most comfortable journey with heavy luggage, but it works well for budget travellers or those heading to areas along the Piccadilly line corridor.
National Express Coach
National Express operates coaches from Heathrow to destinations all over the UK. There are direct services to Birmingham, Manchester, London, Oxford, Cambridge, and many other cities. Coaches depart from the Central Bus Station near Terminals 2 and 3 and also from Terminal 4 and Terminal 5. Booking online in advance gives the best fares.
Taxi and Rideshare
Official taxi ranks operate outside each terminal. Black cabs are metered and regulated. The journey from Heathrow to central London by taxi typically takes 45 to 75 minutes depending on traffic and can cost anywhere from £50 to £80. Minicab services and Uber are also available from designated pickup zones. The pickup points are clearly signposted at each terminal.
Chauffeur Service
If you want a proper stress-free start or end to your trip, a chauffeur service is genuinely worth considering. It is not just for business travellers either. A lot of people use it for family holidays, long-haul trips, or simply because they do not want to deal with parking, train changes, or lugging bags through a busy station after a 10 hour flight.
With a chauffeur transfer you get a professional driver who meets you at your terminal, helps with your luggage, and takes you directly to your destination. There is no meter running while you sit in traffic wondering how much the final bill will be. You know the price upfront and you book it in advance.
National Executive Transfers offers a dedicated Heathrow Airport chauffeur service covering all four terminals. Their drivers track your flight in real time, so if your plane lands early or runs late, they adjust accordingly. You will not land to find no one waiting. They also offer a broader range of airport transfer services if you are travelling through other UK airports or need a return journey organised at the same time.
For groups, families with young children, elderly passengers, or anyone with a lot of luggage, a chauffeur transfer genuinely takes the edge off what can be a tiring journey. It is worth looking into before your next Heathrow trip.
Heathrow Parking Guide
Heathrow has parking options at every terminal for both short and long stays.
- Short Stay Parking is right next to each terminal. It is the most convenient option for drop-offs and pick-ups or very short visits. Rates are the highest per hour but the closeness to the terminal is unmatched.
- Long Stay Parking is located slightly further away from each terminal but is much more cost-effective for trips of several days. Free shuttle buses connect the long-stay car parks to their respective terminal buildings. Journey times on the shuttle are typically 5 to 15 minutes.
- Meet and Greet Parking allows you to drive directly to the terminal, hand your keys to an approved valet driver, and have the car waiting for you when you return. It costs more than standard long-stay parking but is very convenient.
Always book parking in advance. Heathrow parking prices rise sharply the closer you get to your travel date. Booking several weeks ahead can save a significant amount. Use the official Heathrow website or a trusted comparison site to check current rates.
If parking stress is not something you want to deal with, another option is to skip it entirely and book a Heathrow chauffeur transfer instead. You get dropped right at your terminal door and picked up from arrivals when you land. No parking fees, no shuttle buses, no dragging bags across a car park at 5 in the morning.
Lounges at Heathrow
Access to airport lounges can genuinely transform the pre-flight experience. Here is a summary by terminal:
- Terminal 2: Plaza Premium Lounge, No1 Lounges, and various airline-specific lounges for Star Alliance premium passengers.
- Terminal 3: The Virgin Atlantic Clubhouse (outstanding), Qantas London Lounge, Cathay Pacific First and Business Class Lounges, and independent lounges including No1 Lounges.
- Terminal 4: Qatar Airways Premium Lounge and Etihad Airways Lounge. Both are highly rated and among the best in the airport.
- Terminal 5: British Airways Galleries Club, Galleries First, and the Concorde Room for First Class passengers. These lounges are all well-regarded and match the premium standard expected at this terminal.
Independent lounges across terminals are accessible via Priority Pass, DragonPass, or direct payment. Day rates are typically between £35 and £60 per person depending on the lounge and time of day.
Facilities Across All Heathrow Terminals
All four terminals share a core set of facilities that make travelling easier regardless of which one you are using.
- Free WiFi is available throughout all terminals. The connection is reliable enough for most everyday needs.
- Baby Changing Facilities are found before and after security in all terminals. Some rooms include separate nursing areas.
- Prayer Rooms and Multi-Faith Spaces are available in every terminal. They are quiet and available to all passengers regardless of faith.
- Accessible Facilities are comprehensive across all terminals. Lifts, travelators, accessible toilets, and wheelchair assistance are all well provided. If you need special assistance, contact your airline at least 48 hours before travel to arrange support.
- Lost Property has two main offices. The primary one is near the Underground station for Terminals 2 and 3 on Level B. Terminal 5 has its own office in the arrivals hall.
- Currency Exchange and ATMs are in every terminal both before and after security. Travelex operates multiple locations across all four buildings.
Top Tips for Heathrow Travellers
- Know your terminal before you leave home. This one point alone removes the biggest stress for most people. Check your boarding pass, check the airline app, and confirm it the day before.
- Arrive with enough time. Long-haul needs 3 hours minimum. Short-haul needs 2 hours. Add more during school holidays, bank holidays, and summer season.
- Use the Elizabeth line. For most travellers coming from London it is the best balance of speed, cost, and convenience.
- Book parking early. Heathrow parking prices increase week by week as your travel date gets closer. Booking 4 to 6 weeks ahead can save you £30 to £50 or more.
- Check your gate before leaving the lounge or restaurant. Heathrow posts gate numbers roughly 60 to 90 minutes before departure. Some gates need a 10 to 15 minute walk to reach, so head there as soon as your gate appears on the screen.
- Allow 90 minutes or more for inter-terminal connections. If you land in one terminal and your connecting flight leaves from another, do not assume 45 minutes is enough. At Heathrow it rarely is.
Download your boarding pass. Nearly all airlines at Heathrow accept mobile boarding passes. It saves time and means one less thing to worry about losing.
Final Thoughts on the Heathrow Airport Terminal Guide
Heathrow is a genuinely impressive airport. It connects the UK to more than 200 destinations and handles more international passengers than almost anywhere else on the planet. But its size and multi-terminal layout mean that a little preparation goes a long way.
Know which terminal you need. Arrive on time. Check the transport links in advance. And give yourself enough breathing room between landing and connecting to avoid any unnecessary stress.
Whether you are flying Star Alliance from Terminal 2, catching Virgin Atlantic from Terminal 3, boarding a Gulf carrier at Terminal 4, or flying British Airways from the iconic Terminal 5, Heathrow has everything you need once you are in the right place.
Safe travels from whatever terminal your journey begins.
