When flights get cancelled because of heavy winds / bad weather, why is it only e.g. 10% of all flights and not 100%? Isn’t either too dangerous so no plane can take off or it’s safe so they all can take off ?

TLDR Answer.

One Major Reason is Timing: When conditions are not perfect, they space the planes out farther for safety. Longer time between takeoffs, landings, longer following distances. So you can’t fit as many planes into the air. That means some will have to be cancelled to help avoid a domino effect of delays.
