I just got an email from Virgin Atlantic's P.R. rep announcing a three-day fare sale starting this morning and going through Thursday on airfare between Los Angeles and London. Travel dates are January 10 - March 26. The email said the fares were as low as $296 each way based on a round-trip purchase plus up to $250 in government taxes and fees. That would be a total of $842. But on the Virgin Atlantic website I found a total round-trip airfare of $711 for a departure on February 20 and a return on February 27. That same fare was also available on other travel dates. That's a very good airfare from L.A. The best competitive price on those same travel dates I found using Kayak was $827 on Delta, which is a decent fare in itself.
A word about Virgin's pricing policies. The airline was just fined $50,000 by the Department of Transportation for not clearly stating total airfares, including airline surcharges and government taxes and fees. They seem to have fixed that oversight.
