I'm an AS nobody, but I have an HA inter-island flight early next year that I was planning to credit to AS for fun to see if the 500 minimum still applies. I called HA about a month ago to add my AS FFN to the reservation and they did, but it still showed up online as an HA FFN on the flight management page. As of today, it shows up as AS (I'm too new here to add a photo, sorry). In the guest info, AS also appears as an option in the drop-down menu now, but prompts to call HA reservations department to add it.
