Navigating Heathrow’s Four Terminals
Heathrow has four separate terminals, and it is critical to know which one your airline uses as they are spread out. The terminals are generally organized by airline alliance.
- Terminal 2 (The Queen’s Terminal): This is the primary home for Star Alliance airlines. You will use this terminal for Lufthansa, Singapore Airlines, and Air India.
- Terminal 3: Primarily serves Oneworld alliance airlines, including Qatar Airways and Cathay Pacific. It’s also used by Emirates and Virgin Atlantic.
- Terminal 4: This terminal is home to the SkyTeam alliance (like KLM, Air France) and several other non-aligned carriers.
- Terminal 5: This is the exclusive, state-of-the-art terminal for British Airways and its sister airline, Iberia.
Connecting Flights & The “Heathrow Shuffle”
Connecting flights at Heathrow often requires changing terminals, a process sometimes called the “Heathrow Shuffle.” Allow plenty of time.
- Follow “Flight Connections”: After you deplane, follow the purple “Flight Connections” signs.
- Inter-Terminal Transfers: Free shuttle buses operate between all terminals. Follow the signs for the bus to your next departure terminal.
- Security: You will have to go through a security checkpoint again as part of the connections process.
- Immigration: Depending on your itinerary, you may need to go through UK passport control. If you are transferring between certain terminals or have a long layover, this may be required.
Transportation Between Heathrow and Central London
Heathrow has excellent public transport links to the city.
- Heathrow Express: The fastest way to Central London. It’s a non-stop train service to Paddington Station that takes just 15 minutes, but it is the most expensive option.
- Elizabeth Line: A fantastic newer option. These modern trains are comfortable, have Wi-Fi, and will take you to key central locations like Paddington, Bond Street, and Canary Wharf in about 30-45 minutes.
- London Underground (The Tube): The most budget-friendly option. The Piccadilly Line serves all terminals and takes about 50-60 minutes to reach Central London.
- Taxis & Ride-Sharing: London’s iconic black cabs are available, as are app-based services like Uber and Bolt, from designated pick-up areas.
Final Tips for Navigating LHR
- Triple-Check Your Terminal: This is the most important tip. Your arrival and departure terminals can be different. Check your booking carefully.
- Allow Extra Time: Heathrow is famously busy. We recommend a minimum of 3 hours for an international connection.
- Use Contactless Payment: The easiest way to pay for the Tube, Elizabeth Line, and buses is with a contactless credit/debit card or a mobile payment app.
FAQs
