These direct flights change each year. AA had SJU-DFW-ANC in the past, obviously the dates are the same as the DFW-ANC season (June-September). Whether this will be offered in 2006 remains to be seen. AA has had some interesting direct flights, things like Hawaii-Florida (various cities) and LAX-SXM (with 2 stops and not on the transcon list). But these flights rarely recur, I suspect AA adds the routing in response to some specific competitive situation and this doesn't last from year to year.
