What This Means
That is the lowest tier in the release, and it already reaches Alaska. The broader 400-point tier is small, but Alaska is the best region in it by score, which is the important part.
If you want a more comfortable Alaska setup, 600 and 800 points both improve the inventory depth without changing the basic conclusion. By 1,200 points, balcony access appears, and Alaska becomes the clear center of gravity for the tier.
For Alaska, the threshold is low this month. 400 points gets you in the door. 1,200 points is where the itinerary starts to look materially better because balcony inventory opens up. If you are planning around Alaska specifically, this release is favorable at the entry level.
