Flights are generally not cancelled due to windy conditions. Airlines typically cancel flights due to extreme wind gusts, which can exceed 80-100 mph. The FAA requires that if wind gusts exceed 75 mph, the aircraft must be pulled back from the runway and proceed to a designated holding area until the conditions improve. Pilots must also consider the crosswind component when determining if a flight can safely depart. If the crosswind component is not within the aircraft's certified limits, the flight will be cancelled for safety reasons.
