PSA for anyone wondering about personal item sizing:

I recently flew Alaska Airlines on a Boeing 737 and brought my Yeti M12 Hopper backpack as my personal item. It does fit.

For reference:

- It slid under the seat in an aisle seat, but just barely. I had to angle it (definitely snug, first pic)

- It fit much more comfortably under a middle seat (2nd pic)

If you’re planning to use it as your personal item, you should be fine, just don’t overpack it to the point where it loses flexibility. Sharing since I was stressing about this before my flight and couldn’t find a clear answer.
