After clearing transit passport control and security, I had a 3 hour connection, and no gate was posted yet for my flight. I decided to head to the British Airways first class lounge on the south side of the airport.
British Airways has business class, first class, and Concorde Room lounges. The Concorde Room is their ‘real’ first class lounge which is open only to BA’s first class passengers (and a select few elites). Business class passengers use the business lounge. So the ‘Galleries First’ first class lounge is really a ‘top tier elite lounge’.
