I'm much less happy with BA now.
As mentioned before, I was really impressed that BA stumped up sufficient ££ to cover most of our actual loss after they lost three of our four bags between T5 and Austin and delivered them with a lot of stuff missing.
This was answered after a month or so and the essence of it was 'sorry, nothing we can or will do'.
I rang the Gold line to confirm BA's stance before launching into verbal and internet commenting and was essentially told that whilst BA empathised, the policy is not to give Avios for baggage issues, this is immovable and words to the effect of we realise that you have a choice (i.e. poke off if you want to).
I was happy with the financial attempt to make things right, but we're still worse off compared to the situation if BA had not mishandled the bags and items had not been pilfered. Given BA give out Avios if the IFE is flaky to keep customers happy and loyal, I thought it was likely they'd offer something for the emotional consequences of the baggage faff. I was wrong.
So, in line with the guidance from the Gold line, as I have a choice, I cancelled a booking next week to Bordeaux with BA and rebooked with easyJet as a start!
