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.

Currently, Dunkin’ says it has nearly 90 airport locations and more than 50 train and bus terminal locations up and running for this holiday season. Plans call for another 12 airport locations to open during 2013, the chain added.

Motorists will also have a chance to tank up on Dunkin’ joe; Dunkin’ products are now available at rest stops along such major roads as Florida’s Turnpike, the Maryland Turnpike, the Connecticut Turnpike, Merit Parkway, and the Kansas Turnpike.

‘‘Airport and other non-traditional locations continue to be strong growth areas for Dunkin’ Donuts,’’ Grant Benson, vice president of development at Dunkin’ Brands, the chain’s parent company, said in a statement.
