These discount B fares are new and intended to be a way for them to better merchandise E+ -- an E+ seat assignment will be included at no charge. They started to appear a couple of years ago domestically, but this is the first time I've seen them TATL. (That's why the B fare is different on the two flights on November 1 -- it's priced as a differential from the lowest-available economy fare).
