hi, thanks for all the replies.
We got bumped up to CW once but not with the kids. We also try to fly PE with Virgin and FC's SCP etc, so do like a little bit of luxury.
I will ask about availability a little nearer the dates. The BA site says we will be allocated seats 3 days before we fly but I suppose what we get depends on what's been reserved by the full fare payers and gold card execs??
