I wouldn't be so sure of that, LD12986. By its very nature, the people who contribute here are likely to be sufficiently interested to still be contributing a year later. A great many more switched off months ago. Those people may well be rolling their eyes and silently switching their bookings to another carrier. Chances are, people have gone beyond the "I'm NEVER booking with them again" point and have already chosen elsewhere.
It will damage BA, no doubt about it.
