I was in Frankie & Bennys Restaurant last week and the staff were talking about:
It was closing (and they lose their jobs) and would be converted to the new BA Lounge. BA Lounge would also incorprate the current No 1 Lounge (located next door) and the No 1 Lounge would relocate to larger premises downstairs.
The current No 1 Lounge is always full during the peak flight departure hours and space in any case is limited. Priority Pass members aren’t welcome unless they have pre-booked and rumour has it is not so easy to do online? I actually went to Frankie & Bennys as no access available to the No 1 Lounge for Priority Pass ‘walk-ins’
