Hi all, I was booked to fly from LHR to MAN on Friday eve (BA1406). The flight was ultimately cancelled and then my bag wasn't returned. I've filled in the online form and I know I just have to wait now, but I just have a couple of probably basic questions about the process.

The text and email I had from BA acknowledging the claim have links to two separate websites - worldtracer and a BA missing baggage page. The reference number I have (which starts with LHRBA) is recognised by the worldtracer website but not thr BA one. Why would that be the case? Also, I read somewhere that the status on the missing baggage websites is updated in batches. What does that mean and how often is it done?

Thanks in advance for your help. Think I've been lucky in not having had this happen before!
