The American Airlines reduced mileage award destinations have been released for December 2013 and January 2014. They have now listed the locations by alphabetical order by airport code instead of region which makes it easier to find I think. Below are the locations for these months.
Below is the mileage table for rewards to the above destinations and a reminder that you can now book one way awards.
Some notable cities include Aspen, CO for skiing/snowboarding and Key West, Fl for the snow birds who fly south for the winter. Canadian locations are still on the list.
