Terminal Overview
Heathrow Terminal 1 is not in operation. London Heathrow Airport (LHR) currently runs four terminals: Terminal 2, Terminal 3, Terminal 4, and Terminal 5. If your booking, older document, or third-party website mentions “Terminal 1,” treat it as outdated information and confirm your actual departure/arrival terminal directly with your airline or on your booking manage page.
In practical terms, what “Terminal 1” used to handle has been absorbed into the airport’s current terminal structure. Today, Terminal 2 largely serves Star Alliance and many European/international carriers, Terminal 3 is a major long-haul terminal with a wide mix of airlines (including Virgin Atlantic’s hub), Terminal 4 hosts a smaller set of international airlines, and Terminal 5 is primarily the British Airways hub (plus Iberia). Your experience at Heathrow now depends entirely on which of these four terminals your flight is assigned to.
Airlines & Destinations
- Terminal 2 (The Queen’s Terminal): Commonly used by Star Alliance and partner airlines. Airlines include Lufthansa, Swiss, United, Air Canada, Singapore Airlines, Turkish Airlines, TAP, LOT and others. Destinations span Europe plus long-haul services to North America, Asia, and beyond.
- Terminal 3: A long-haul-heavy terminal with airlines such as Virgin Atlantic, American Airlines, Delta, Emirates, Cathay Pacific, Japan Airlines, Qantas and more. You’ll see major routes to the U.S., Canada, the Middle East, and Asia.
- Terminal 4: A smaller international terminal with airlines including Malaysia Airlines, Oman Air, El Al, Tunisair and others (operations can be specialized and may vary).
- Terminal 5: Primarily British Airways (its main hub) and Iberia, covering extensive UK/domestic, Europe, and long-haul networks.
Alliance-wise, you can generally think of it this way: Star Alliance is strongly associated with Terminal 2; SkyTeam carriers are prominent in Terminal 3; and Oneworld is split between Terminal 3 (some carriers) and Terminal 5 (especially BA/Iberia). Because allocations can change, always verify the terminal shown on your boarding pass or airline app.
Layout & Navigation
Because Terminal 1 is closed, your “Terminal 1 plan” should really be a plan for navigating between the active terminals. The airport is effectively grouped into three areas: Heathrow Central (Terminals 2 and 3), Terminal 4 (south side), and Terminal 5 (west side). If you arrive at the wrong place, don’t panic—Heathrow is built for inter-terminal moves.
- Terminals 2 ↔ 3: Connected by a pedestrian walkway that typically takes about 10 minutes on foot.
- Heathrow Central ↔ Terminal 4: Use the free shuttle bus from the central area (around the Terminals 2/3 rail station zone).
- Heathrow Central ↔ Terminal 5: Use free rail connections (Heathrow Express/rail transfer within the airport). The Underground also links terminals, but rail transfers are usually the most direct inside the airport.
Gate details vary by terminal and airline. Where published, Terminal 2 includes gate areas such as A16, A17, A21–A23, A26 and B33, B38, B43, B46, B48. If you’re connecting, build in extra time for (1) walking within the terminal, (2) any security re-screening, and (3) the inter-terminal transfer—especially if you’re moving between Terminal 4 or 5 and Heathrow Central.
Amenities & Services
You won’t find services in “Terminal 1,” but Heathrow’s current terminals are well-equipped. Terminal 2 has a strong mix of shopping, restaurants, seating, and airline/partner lounges; Terminal 3 is known for its long-haul lounge lineup (including major airline lounges), dining, and retail; Terminal 5 offers extensive facilities across its main building and concourses; and Terminal 4 provides a smaller, simpler set of lounges, dining, and retail aligned to its flight schedule.
- Lounges: Expect the broadest choice in Terminal 3 and significant options in Terminal 2 and Terminal 5 (especially for BA in T5). Availability depends on airline, cabin, and status.
- Food & shopping: Terminals 2, 3, and 5 have the deepest selections; Terminal 4 is more limited but still has the basics for a meal and last-minute purchases.
- Business needs: Look for lounge work areas, charging points in seating zones, and paid fast-track options where offered by your airline/terminal.
- Family amenities: Heathrow terminals generally provide baby-changing facilities and family-friendly dining; specific play/nursing locations vary, so check terminal maps once you know your terminal.
- Accessibility: All operating terminals support step-free routes and assistance services. If you need help, pre-book assistance with your airline and allow extra time for transfers.
Practical Tips
- First step: confirm your terminal. If anything says “Terminal 1,” assume it’s wrong and verify in your airline app/booking—terminal assignments at Heathrow do change.
- For long layovers: If you’re in Heathrow Central (T2/T3), you have lots of dining and seating and an easy 10-minute walk between the two terminals for more options (as long as you remain on the correct side of security for your itinerary).
- Quietest places: Your best bet is usually deeper into the gate areas away from the central shopping spine, especially outside peak waves of departures.
- Power outlets: Concentrate your search around larger seating clusters near central retail zones and in lounge areas; gates with newer seating are more likely to have outlets within arm’s reach.
- WiFi: Heathrow provides passenger WiFi across terminals. If it’s slow, try reconnecting closer to main seating hubs or switching between networks listed on the sign-in page.
If you tell me your airline and flight number (or just the airline and whether you’re arriving/departing), I can point you to the most likely terminal and the simplest transfer path.
