Citing a jump in airline tickets bought for the upcoming Christmas-to-New Year’s holiday period, Dunkin’ Donuts wants to alert travelers that it now has stores strategically placed at many airports as well as at many bus and train terminals.

The Canton-based coffee-and-baked-goods chain says airport and other “non-traditional locations” continue to be strong growth areas for the company. A chain with 10,000 restaurants around the world says it now has more than 500 Dunkin’ outlets at non-traditional locations.
