Anyone have any bloody idea why prices of flights fluxuate so much so quickly. (Maybe you folks in the travel industry can explain.) mr. nuts and I have a trip to SP planned in Jan/Feb and I check the cost with all the sites fairly often. Expedia had the price at $1143 each yesterday and it's $1153 today....I'm clueless, what gives?

It's never too late to have a happy childhood!
