Access to lounges at London Heathrow (LHR) depends on your terminal, airline, and frequent flyer status. At Terminal 5, the flagship home of British Airways, you can use the Galleries Club or First lounges if you are flying in a premium cabin or hold OneWorld Sapphire/Emerald status. At Terminal 2 (The Queen's Terminal), Star Alliance members have a wealth of options including the high-end Lufthansa Lounge, the Singapore Airlines SilverKris Lounge, and the United Club. At Terminal 3, OneWorld members can access the award-winning Cathay Pacific Lounge and the Qantas London Lounge, while American Express Platinum cardholders have access to the Centurion Lounge. If you do not have elite status or a premium ticket, you can "pay-per-use" at a Plaza Premium Lounge or use a Priority Pass membership to access independent lounges like the "No1 Lounge" or "Club Aspire." In 2026, many of these lounges now offer "pre-booking" services to guarantee a seat, which is highly recommended as they can become crowded during peak departure windows.
