After all it's lift created by sufficient airflow and angle of attack (or at least drag) of some sort, whether kites, gliders, powered aircraft or sharks in a sharknado. The first (unless connected to the ground as pointed out by SSD) and the last only "fly" in an updraft strong enough, so potentially misleading example. Anyway, an aircraft in flight only cares about moving through an air mass with sufficient speed ("airflow due to airspeed"), not whether that air mass itself is moving relative to the ground ("airflow due to wind").
