Being BAEC Silver I will fly FRA-LCY in Economy next week and would like to try a different lounge at FRA for a change. Will I get to choose or will I have to use the "designated" BA lounge? The oneworld website suggests the former: passengers "with oneworld Emerald or Sapphire status can use any lounge offered by any oneworld airline when departing on any flight marketed and operated by any oneworld member airline." I still concerned that the lounge agent may turn me away from, say, the Cathay Pacific lounge. Do you have any recommendations where to go? My flight is at 7 a.m. Thanks, ps
