I agree with the person above that it isn’t worth it for a short flight like this one, but we might like to do it for a flight to New York using our companion fare voucher.
Apparently you have to call in...

Only 15,000 miles to upgrade to First Class.2
To shop for fares that qualify for a mileage upgrade, and to view available space and eligibility, please select Mileage upgrade as your Upgrade preference option when shopping for flights.
Once your ticket is purchased, redeem a First Class upgrade award by calling Alaska Airlines reservations at 1-800-252-7522.
Upgrades can also be requested, if available, within 24 hours of your flight departure through online check-in or on the day of departure at an airport check-in kiosk.
Check out what First Class has to offer and how to pay for an upgrade.
In case it hasn't become clear yet, this is a terrible deal. I let every single companion certificate I ever got expire unused, and I have zero regrets.
