Do NOT introduce business class with free middle Seat instead of SAS plus service. This is a mile step backwards as planes take fewer passengers.

Let people on the plane as they are seated, start with A and F, then B and E, and then C and D at last.

Stop Printing menus for biz class, make them available on the monitor.

On your flights, start sharing how much of that flight is powered by biofuel purchased by customers flying.

Keep a updated and modern fleet of aircrafts.

Donate unused food and beverages after flights and try to get closer to zero food waste.
