Thanks for this brilliant explanation, 13901 - it helps me understand and rally confirm my suspicion that it all ‘magically’ happens due to the barcodes.

I really, really hope you’re right regarding the fact that it should now make the BA289 today, however as we approach 04:30 here in Phoenix and 12:30 in the UK the baggage claim portal system thingy is still showing as searching for my bag.

I understand what you mean by the AirTags pinging off the signal, but it’s been intermittently refreshing over the last 12 hours and so is pinging off something and although it has moved within the structure a little it is still sitting in there. Somewhere.

it may be coincidence that both the bags allocated to MrGB when AWOL, and I’m still totally unsure how one of them could have ended up in LYS! I just hope you’re right that the system just does it’s thing and it gets loaded today.
