How common are free flight upgrades?

Are the days of sweet-talking check-in staff to get a free upgrade to premium economy, business, or first class, long gone? Many airlines now sell spare upgrade capacity at the desk. So we want to see how common they are.

Please answer the closest to your situation for flights in the past two years.
