It's all being incredibly civil, isn't? I think we all deserve a round of applause!

Anyway, ppp909, I did indeed understand the concept you envisage. But my immediate reaction was the variables involved. The message would surely be ...
"Yes, as a valued GCH we will probably waive the rules for your forthcoming trip, but then again we might be busy then so we might not."

It's a personal thing, but when we go travelling we like a high level of certainty. I wouldn't be very happy with aspects of our travels involving "it might happen, and then again it might not". I will, of course, make an exception where upgrades are concerned

Anyway, since BA/BAEC seem incapable of communicating accurately in many different areas, I would still have doubts about the sufccessfuhl and accurate application of your idea.
