I’m neutral (GGL partly through business travel) albeit it’s slightly negative for my immediate family (GCH though leisure travel).
However for many of my colleagues (we often fly last minute long haul flexible fares) these changes will move them up a tier from where they currently are. They aren’t avgeeks of any kind so won’t be aware of the debates, they will simply recover a higher level of service from BA and be happy about it. Seems reasonable that BA values their £50k+ spend more than it values £3k, even though the old tier point model says otherwise.
