Whether you are flying for the first time or you are a seasoned business traveller, understanding Heathrow Airport's terminal layout is essential to a smooth journey. Heathrow is one of the world's busiest airports, and knowing how many terminals it has, which airlines use each one, and how to get between them is key to navigating it.
This comprehensive Heathrow Airport terminal guide covers everything you need to know — from terminal-by-terminal airline listings to inter-terminal transfer times, transport options, facilities, and how to book a reliable taxi or private transfer to any Heathrow terminal.
How Many Terminals Does Heathrow Airport Have?
Heathrow Airport currently operates four active passenger terminals: Terminal 2, Terminal 3, Terminal 4, and Terminal 5. Terminal 1 was permanently closed in 2015 and has since been demolished to make way for future development.
Each terminal caters to a specific group of airlines and routes, making it crucial to know the terminal your flight departs from or arrives into as the first step in planning your airport experience. Getting this right avoids unnecessary stress, missed check-in deadlines, and confusion on arrival.
Here is a quick overview of each active Heathrow terminal and what it handles:
• Terminal 2 — Open, serves Star Alliance and partner airlines
• Terminal 3 — Open, serves Oneworld, SkyTeam, and independent carriers
• Terminal 4 — Open, serves SkyTeam, Gulf carriers, and selected airlines
• Terminal 5 — Open, serves British Airways and Iberia exclusively
Heathrow Terminal 2 The Queen's Terminal
Terminal 2, known as the Queen's Terminal, opened in 2014 and is home primarily to Star Alliance member airlines. It is one of the most modern facilities at Heathrow and handles a large volume of long-haul and short-haul international traffic.
Which Airlines Use Heathrow Terminal 2?
Terminal 2 is the Heathrow base for a wide range of international carriers. Airlines currently operating from Terminal 2 include:
• United Airlines

Terminal 2 offers an extensive range of passenger services, including premium airport lounges, duty-free shopping, restaurants, and dedicated zones for families and passengers with reduced mobility. Baggage reclaiming and security screening at T2 are well organised, with multiple lanes to manage peak-hour passenger flows.
Heathrow Terminal 3 International Hub
Despite being one of Heathrow's oldest terminals, Terminal 3 has undergone significant modernisation in recent years. It handles a broad mix of OneWorld, SkyTeam, and independent carriers, particularly those serving the Americas, the Middle East, and Asia.

Heathrow Terminal 4: SkyTeam and Gulf Carriers
Terminal 4 is situated slightly further from the main terminal campus and is served by its own dedicated Heathrow Express and Elizabeth line station. It primarily handles SkyTeam alliance carriers and a selection of Gulf and independent airlines.

Terminal 4's relative separation from T2, T3, and T5 means that passengers making connecting flights should allow ample transfer time, ideally a minimum of 90 minutes for international connections. The terminal has recently undergone improvements to its departures lounge, passenger services, and retail concourse.
Heathrow Terminal 5 serves British Airways and Iberia.
Terminal 5 is Heathrow's largest and most architecturally impressive terminal, designed exclusively for British Airways and its partner Iberia. It handles tens of millions of passengers annually, making it one of the busiest single-airline facilities in the world.
Which Airlines Use Heathrow Terminal 5?
Terminal 5 is home to just two carriers, though between them they operate a vast global network of routes:
• British Airways — all short-haul, long-haul, domestic, and international routes
• Iberia — selected European and transatlantic routes
Terminal 5 is made up of three interconnected buildings, the Main Terminal (T5A), T5B, and T5C, linked by a dedicated internal transit system. Passengers connecting between T5 buildings do not need to re-clear security. British Airways operates its flagship Concorde Room and Club lounge facilities here, widely considered among the best airport lounges in the world.
How to Transfer Between Heathrow Terminals
Understanding the best way to transfer between Heathrow terminals is crucial if you have a connecting flight or need to switch between arrival and departure points. Heathrow offers several free inter-terminal transfer options, and choosing the right one can save you significant time.
Heathrow Terminal Shuttle Service Free Buses
The most commonly used method for transferring between terminals is the free Heathrow inter-terminal shuttle bus. These buses run 24 hours a day, seven days a week, and connect all active terminals on a circular route. Wait times are typically between 10 and 20 minutes between services.
The shuttle stops at designated points outside each terminal. Look for the Heathrow Airport terminal bus signs, which are clearly marked in blue and white throughout the airport campus. The service is completely free of charge for passengers travelling between terminals.
London Underground Heathrow Terminal Connections
The London Underground Piccadilly line connects Terminals 2, 3, and 5, as well as Terminal 4 on a separate loop. This is an excellent option for transferring between terminals, particularly during peak hours when road traffic around the terminal forecourts can be slow. Trains run frequently throughout the day and into the early hours of the morning.
The Elizabeth line also serves Heathrow Terminals 2, 3, and 4, providing fast rail connections to central London as well as facilitating terminal-to-terminal transfers for those travelling between the south campus terminals.
Heathrow Airport Terminal Transportation Options Estimated Transfer Times
Transfer times between terminals vary depending on your route. Here is a general guide to help you plan your journey:
• Terminal 2 to Terminal 3 — approximately 10 to 15 minutes by bus or tube
• Terminal 2 or 3 to Terminal 4 — approximately 20 to 30 minutes by tube
• Terminal 2 or 3 to Terminal 5 — approximately 15 to 25 minutes by bus or tube
• Terminal 4 to Terminal 5 — approximately 25 to 35 minutes by tube
• Terminal 5 to Terminal 2 or 3 — approximately 15 to 25 minutes by bus or tube
These are transit times only. Always factor in additional time for security screening, baggage reclaim, and walking distances within each terminal building.
Is Heathrow Terminal Transfer Free?
Yes, the inter-terminal bus service and the London Underground services between Heathrow terminals are free of charge for passengers in transit. However, if you exit the airport complex and re-enter, you will be subject to normal Tube fares. Always confirm with ground staff whether your transfer requires you to clear customs and re-enter security, as this significantly affects your required transfer time.
Heathrow Airport Terminal Facilities and Services
Each Heathrow terminal is a self-contained passenger environment with a full range of services. Here is a summary of what you can expect across all terminals.
Airport Lounges
All four Heathrow terminals have premium airport lounges accessible to business class passengers, first-class travellers, and frequent flyer programme members. Facilities typically include reclining seating, shower rooms, hot and cold buffet service, full bar service, Wi-Fi, and quiet zones for working. Terminal 5 is home to the British Airways Concorde Room, which is consistently rated among the finest airport lounges globally.
Check-In Desks and Bag Drop
Check-in desks at all Heathrow terminals open between two and three hours before departure for most airlines. Self-service kiosks and automated bag drop facilities are widely available, reducing queue times significantly. Always confirm your check-in terminal with your airline before travelling, as some carriers operate from specific zones within a terminal building.
Retail, Dining, and Duty-Free
Heathrow Airport is one of the world's premier retail destinations. All terminals feature extensive duty-free shopping, luxury brand boutiques, high street retailers, and a broad selection of restaurants, cafes, and bars. Terminal 5 in particular is noted for its curated luxury retail experience, with a range of designer and premium brands operating within the departures concourse.
Heathrow Airport Terminal Parking
All Heathrow terminals have direct connections to short-stay and long-stay parking options. Heathrow Airport terminal parking is available to pre-book online at a discounted rate, with shuttle buses running between car parks and terminals at regular intervals. Short-stay car parks are ideal for drop-offs and collections, while long-stay options offer better value for passengers travelling for extended periods.
Heathrow Airport Taxi and Transfer Services
For many travellers, the most convenient and stress-free way to reach any Heathrow terminal is by pre-booked private transfer or taxi. Whether you need a taxi to Heathrow Terminal 2, a chauffeur service to Terminal 5, or a minicab pick-up from Terminal 4 arrivals, a professional Heathrow Airport transfer service offers door-to-door convenience that public transport cannot match.
Why Book a Private Transfer to Heathrow?
There are several compelling reasons to book a Heathrow Airport private transfer or minicab service rather than relying on public transport or street taxis:
• Fixed pricing with no surge charges, regardless of traffic conditions or time of day
• Meet-and-greet service available at all four Heathrow terminals
• Flight monitoring includes your driver tracking delays and adjusting pick-up time automatically.
• Suitable for families, groups, business travellers, and passengers with excess luggage
• Available 24/7, including early-morning and late-night airport runs
• No waiting in taxi queues after a long-haul flight
Heathrow Airport Terminal Pickup and Drop-Off
Each terminal has designated taxi and private hire pickup zones that are clearly marked and separate from the main public transport interchanges. For drop-off, the terminal forecourts operate a zero-waiting policy, so pre-booked services will coordinate a precise pick-up point in the official taxi rank or meet-and-greet zone.
Pre-booking your Heathrow Airport transfer ensures you are assigned a specific driver, receive a confirmed vehicle, and travel at a fixed price, removing the uncertainty of hailing a street taxi or joining a long minicab queue after arrival.
