MMB is saying BA has a lounge in T3. The location described is where BMI used to have their lounge, but does anyone have an explanation at why BA is showing this?
British Airways Lounge
The lounge is located after Security. Turn left, follow signage for T3 Departure Lounge, then the BA Terraces Lounge is at the bottom of staircase, next to the lift. (Lounge access is subject to capacity restrictions.)
