As both a SEA-MIA cruise ship flyer and latin america access flyer, this flight has NEVER worked out well!

If it left SEA at 6AM, it would be good for both. But instead they fly a couple hours later, and arrive MIA after the cruise ship cutoff times and the last flights fly for the Caribbean and Latin America, forcing a MIA overnight.

Making this a red-eye simply competes with all the other redeye flights available (albeit with stops).

To make this flight competitive, AS MUST depart SEA 5:30AM or 6AM. IMO.
