Had almost almost 2 years of not much flying so have dropped down to silver and now bronze. Was on my first BA flight for almost a year yesterday and the very apologetic CSM mentioned that she had a note to ask why my status had dropped and whether I'd been flying other airlines.
I rarely got the greeting as a GCH (I think mainly due to the routes I was flying), but was nice to see BA being proactive here. What they do with the information is another matter...
