The BI BWN lounge is pretty bad considering there was a scheduled connection exceeding 12 hours on my LHR-DXB-BWN-MEL ticket and no couches at all that would accommodate a quiet nap...food was average too.
Going to disagree with this one. It's a clean, quiet lounge and never crowded. While there aren't any 'nap' areas and the food and drink options are quite paltry, I can think of a number of worse lounges.
PS, the flight timings have now been changed for LHR-MEL with the connections a lot shorter.
