I too suffered T5 last night - not too bad a show from BA given the high number of cancellations. A nice bed for the night and a new ticket for this morning although would have been easier to announce canx at 19.45 rather that 21.00 when we were unlikely to land in GVA anyway.
Highlight of the evening was being dealt with by Jeremy Spake at the BA Cust Service desk - is he T5's latest weapon ??
