I've been monitoring airfare for quite some time and wasn't seeing anything less than $815 and decided to name my own price on Priceline.com. Dates: Aug. 3-24 From Los Angeles International Airport to London Heathrow Three tickets I put in a bid for $625 and received a counter offer for $725.28. I went for it! Flight times are good with a 2 hour layover in Houston. I'm pleased with the outcome.
