There are also the 'trans-con' AS flights that are not on the list, LAX-NAS, LAX-SJO, SEA-CUN all over 2500 miles. I would not expect AS to have any D space on the JFK-ANC flight. When I checked that flight last year, it was a random D1 on very few days.
Last year I flew JFK-LAX-NAS-LAX-ORD-ANC-DFW. I doubt that one can earn much more in the miles category.
