But I think someone reported having success on an international BE fare, so YMMV. The "international" definition only excludes flights to/from Caribbean and flights between US states and territories.

This is the confusing part - the wording is in fact diametrically opposed to each other... Your interpretation would make sense but I wasn't able to get a official yes or no from DL.
