Following my recent demotion to bronze, the difference for me is nil. If anything, I would probably pick easyjet over BA now because they do a better job of providing an LCC service.
BA does differ if you have status or are in CE, but at the back of the plane they are the same as the rest.
I will still fly ba where they are the cheapest or most convenient, or where rfs makes sense. But I would no longer pay a premium to do so.
