Interesting, but I think it might be worth a crack at contacting BA/Avios to see if they are willing to cooperate with us and provide a fresh list whenever they update. That would be far easier and much more accurate.

It would take one of their techs about 5 seconds to produce and could probably easily be automated after that.

After all, it's going to bring them more revenue, which is good right?

I will PM Nicci and see if she can point me in the right direction.
