Thank you - I'll try customer services again. When we were still away they told us on day 4 that they weren't liable as they had evidence now (not on days 1-3!) that the bags had been loaded on our flight to Milan and therefore they had no liability or responsibility after that. They said for example another passenger could have picked them up. Is this right that once the bags are loaded onto a flight BA ends its liability? If so, why were we told to buy essential items and keep receipts by executive club and the Twitter team?
I'm very confused why the stance changed and why it is denied. Customer services also said the bags were to Milan only despite our luggage tags showing all the flights (and several staff saying the tags were all the way through). I will try travel insurance but the limit is low - we had to buy items on an expensive Med island with little choice.
On the other story we asked the BA ground crew for the transfer and hotel as she was helping another group on another reroute. She said we weren't on her list. I asked her if she was going to leave two women at the airport (midnight) and she walked off. We had to get our own taxi to LIN and slept on the floor there as our next flight was 6 am and there was no airport hotel! The re routing staff at LHR assured us there would be help.
