Essentially if you go in July, you'll start with fares from $403 each way. Through August fares start at $429, but after August the fare drop significanlty, usually by at least $100. See the sale page for full details. Virgin says these are their lowest London fares, and I'm believing them. Best of all, they are from 10 major U.S. cities from coast-to-coast.
