I spent a million this year - London to Japan, London to Chicago, London to Sydney (via SIN) all in F for two passengers - along with some GUF and 2-4-1 benefits. Now have basically none left. :-}
Focus on where you want to go and why. Then see what's actually available in First first, Club if not. Setup some alerts on BA Redemption Finder and bite the moment they come to be - because when you go is critical for many destinations too.
