Ultra spammy title thread, huh?
http://www.flightcentre.co.uk/flashsaleFlight Centre are doing a one day sale of return flights to Vegas with Virgin for £308. It doesn't say on the web page, but I would imagine there are lots of restrictions with dates and that, but they probably don't tell you that until you phone up, which gives them a chance to upsell you with other stuff, but might be worth finding out more for those interested.
