The
lounge database lists the Blue lounge, which is also the lounge used in
Genius1's
trip report.
But BA links to oneworld that
lists 3 lounges: ANA (landslide), Blue (T1, next to access corrdor to gates 7 to 13) and Lisbon (Terminal 1, near the food court), with the ANA lounge shown as the BA lounge.
The Blue lounge sounds mediocre. Does anyone have experience of using the ANA or Lisbon lounge? I am travelling this evening with a guest.
