Yes, the British Airways Arrivals Lounge in Terminal 5 at London Heathrow is currently open and operational for eligible passengers. Typically, this exclusive space is available daily from 5:00 AM to 2:00 PM, catering specifically to those arriving on long-haul international flights. To gain entry, you must be traveling in First or Club World (Business Class), or be a Gold member of the Executive Club arriving on a long-haul British Airways flight. The lounge is located on the first floor of the Terminal 5 arrivals hall, accessible via the orange lifts. It is highly regarded for its "Hydrotherapy" area, which features dozens of shower suites, allowing travelers to refresh after a red-eye flight. Additionally, the lounge provides a full breakfast buffet, a dedicated work area, and even a clothes-pressing service. It is important to note that access is strictly for arriving passengers; you cannot use this lounge if you are departing or if you are arriving on a short-haul domestic or European flight, as the facility is designed to support those transitioning from across time zones.
