According to BA the baggage handling system at Heathrow is now working well. However there is a huge backlog of bags at the airport. BA has a team of 400 volunteers who are working to clear the backlog of around 15,000 bags which have now built up at the airport although reuniting passengers with their luggage is likely to take some time because the bags need to go through enhanced security screening This is now being done manually because BA has been unable to use the Terminal 5 baggage system to process the bags.
