Perhaps on UA, but I just booked on AA/Oneworld for peak summer travel (early August) and there was plenty of availability. Also saw availability for pre-Xmas shopping period in early December and the entire period between. So damn rare to get a fare like this originating in PDX. Flying 77W on the long legs and got to use SWUs both ways. Most pleased (though will probably head north to avoid London's insane tourist hordes.)
(Edited to add; Rechecked AA fare rules (IHX9T1S5). At least as presently constituted (swear it was different last night), this is a summer only fare extending from 30JUN-5SEP.. BA also offering this fare.)
