FC flight price drop!

On taking the advice from this site, I decided to check prices for flights again as STA Travel had been giving best offer of £324 (only available to those under 26 with a youth discount card - undiscounted the prices were more like £350+) previously.  However, it now seems that the flights have plummeted in price to America over the past few days, I'm presuming it's due to due to the recent hurricane.  The best price for my dates (departing Sunday 15th Jan and leaving 24th Jan) to SFO is now £303.80 on Opodo!  If I left on the 16th rather than the 15th, the price comes down to £288.80.  I think I'd pay the extra £15 to get an extra day in San Fran tho.

I really want to buy the tickets now as I know these prices won't last!
