I really don't have any special insight to add here. I frankly don't see AA ending either of these routes and especially not because AS flies them. For example, when AS started flying to BOS, AA immediately reinstated their service to BOS. I cannot think of a route that AA has willingly given up to their semi-partner AS. That said if AA was going to get rid of one of these flights to ANC, I would guess it would be the ORD service.

I really can't remember when these flights are loaded since I seldom fly through ANC to get south. But the December - January time period seems to strike a chord with me. Of course, I could be imagining it. I guess if it was me I would just throw in any two segments to and from DFW and then reissue when the flights are loaded.
