Hi,
Thanks for all the replies.
I will handle this with AA when I go back to LHR on Monday evening. I had no insurance of my own.
However, I do feel that airlines should not make so much fuss over a damaged bag, and because they are together in the OW alliance, they should not start counting whose blame it was and who had committed the original sin. It may well be that BA damaged the bag in the first place al LHR and it arrived damaged at LAX and AA had to replace it. Even Menzies Aviation has OW flyers everywhere and they should have dealt with it. AA did say to have my bag replaced at ARN, as it was my final destination, and rhis is why I asked Menzies Aviation to handle it. I was put in the awkward situation as a BA Gold and OW Emerald to drag my bag around at 10 pm through an almost shut down airport.
