It does sound like you've had a bad run of luck from BA, which exceeds my misfortune, rare though that is. I won't describe this as I'm hated the minute I do, but all I can say is these things may even themselves out and I'm sure there's some good luck with BA just round the corner.

Hopefully they'll announce something concrete sooner or later rather than the bits and pieces so far. From posts on the 'large thread about GCH exit row selection problems', there does seem to be a movement towards charging people more for exit rows etc, but this hasn't been published along with some other possible consequent changes.. to GCH, SCH. I know BA are saying there are no changes etc... but I think it's fair for people to have their doubts as changes to the programme are fairly constant.
