Aircraft performance can indeed be affected by extreme heat. Hotter air is thinner, which can make it harder for airplanes to take off. Airlines and airports may not be overly concerned about this, considering they may have strategies in place to handle these situations, like scheduling flights during cooler times of the day or limiting the weight of the aircraft during hot weather. Some airports, particularly those at high altitudes or in hotter regions, have longer runways to give planes more space to reach the necessary speed for
Extreme heat makes flying harder. Airlines and airports say they aren’t sweating it.
