I have finally received official confirmation, the new temporary "lounge" is the space photographed above, next to Gate 37. One of the messages sent to me before the weekend mentioned Gate 47 - hence my earlier reluctance to share the location. So, from tomorrow - Tuesday, 10 June 2025 the "lounge" facility will be at Gate 37. Turn left after security, take the stairs (or lift) down one floor and the "lounge" is straight ahead. It will open approximately 2 hours before each BA flight.
