Whilest the jet might be "international-capable" (ETOPS), chances are good that it will be a 767-200 (older, three-class aircraft that is subject to mechanical difficulties ~25% of the time out of BOS) or a 757-200, a two-class plane.

edited to add: I 'aim' for the 767 and always upgrade, from Economy to Business. The food and service are actually quite nice.
