Transited this afternoon from the US via T5 to Brussels. 2 out of 5 bags never made it to Brussels, a large group from my plane was also claiming lost luggage. Luckily the lost luggage desks at Brussels were fully manned, they have been since T5 went in Ops. Pretty sad state of affairs really but I knew that I had a pretty good chance of loosing a bag or two. Hope for the best but expect the worst. As a matter of fact it could have been worse as on departure at LHR we had to sit at the holding point for about 20 minutes because the flight deck received info that an unclaimed bag was on board. A return to the stand and refuelling was a very likely option for a while.
No hard feelings whatsoever against BA or BA staff, they were obviously trying their best to cope with a poorly functioning system.
