I've been watching the fares on Southwest for our honeymoon, (not till October) Last week, the price was 944. Today it's 593. Has anyone else had experience with these price fluxes? I really want to go ahead and snatch up the 593 rate, but it is awfully early... when is the absolute latest I should buy my our tickets? I've read that Southwest will credit you the difference if your purchased fare goes down, has anyone had experience with this?
