You can get an update on your baggage at
www.ba.com, you need to put in your Reference Number in. This is the quickest way to get an updste, because the information is "live". You should also keep receipts if any reasonable items you needed to buy..such as clothing and underwear, toiletries, etc. BA had a terrible problem with baggage handling last year, but the forums seemed to be showing they were getting their act together. Make sure, even if you have given them the information by phone, that you inout on the website where you are and a contact number.
