Free reebooking to earlier flight when avilable. Result in filling up seats, and making it more likely to fill up seats on later flights

Make it possible to buy bio fuel for past trips.

I would use my skills in optimization and deep learning to learn what frequenzies and time schedules that maximizes the load factor of each aircraft in the fleet.

Allow free rebooking on the day of departure to a shorter route or a route with less stops when available, even in low booking classes and without status.

To increase loadfactor, sell standby memberships to youth passengers who are by nature more flexible. Stable revenue for SAS, increased load factor, more youth mobility.

Let's start by using SAF at least for domestic flights.
