I'm travelling through T5 today on two different PNR's SOF-LHR-BRU. I wonder if BA will interline the bags for me. No idea where the problems are but sounds like a day to not have to collect and recheck bags. No choice but to travel with check-in bags for me. Presume I wont be reunited with my checked in bag for some time though....4 hours between flights which helps. Rather spend it in the lounge though!
