I just noticed the same thing! It makes it kind of hard to price out a trip at this point! I tried clicking on the calendar icon and it brings up a calendar for December 2011, but no matter what month or date I click on it still displays December 2009. I thought, well maybe it's just displaying wrong but will actually use the date I pick, but no, it says "the date you selected has already passed". Crazy! (and frustrating!)
