Late Friday, US Air launched two crazy low sale fares: Las Vegas to London Gatwick ($331 RT incl. tax) and Charlotte (nonstop) to Gatwick ($287 RT incl. tax). Travel is only through late February, but there's just a 3 day advance purchase requirement. I had a dream last night that the sale had expanded to Paris, too, but that was just a dream. What does it mean when you have dreams about airfare sales? Hmmm... guess that's one for the analyst's couch.
