Wearing an ugly sweater today can get you deals on food or onto an airliner ahead of other travelers. It's National Ugly Sweater Day and a number of chains are offering lower prices and freebies. People traveling on Alaska Airlines can get free priority boarding if they wear an ugly sweater. The Alaska Airlines promotion is only today but some of the food and drink deals run through the end of the month and a couple are good into the first week of January. An internet search for Ugly Sweater Day deals will turn up the discounts.
