It seems as if other airlines have moved to match the BA sale fare I reported yesterday.

For example United has a fare from LHR to SFO of £997.10 (a few pounds cheaper than BA) for Business class! Books in Z class (or A for the domestics)

When booking on the UA web site be careful of the cheapest fares as they often include Coach/Economy sectors.

From what I see – Virgin, KLM, Air France, Lufthansa, Delta, Air Canada, Continental, Swiss and bmi have all matched – check Expedia for booking and of course to earn Nectar points.
