In the context of getting miles for F rather than J, it doesn't matter whether routes are "principally" two-class or three-class. A non AA frequent flyer may choose the 772 on that route for the comfort (I know I certainly do), and be disappointed at the earn rate later. It was from that perspective that I pointed out the LAX-MIA frequency, to avoid a potential misunderstanding later.
