Why take off and landing is always against the wind?

Taking off and landing against the wind helps increase lift for the aircraft. When an airplane faces the wind during these phases, the relative airflow over the wings is enhanced, allowing for a shorter distance required to become airborne and improving control during landing. Additionally, landing against the wind reduces the ground speed, making it safer and easier to manage the aircraft's descent and touchdown. Overall, this practice optimizes safety and efficiency in flight operations.
