      No airplane has an air conditioner. They pump cool air into the plane when it is at the sky bridge at the gate. You can see the flexible duct hose that the plane is connected to. Or they have a mobile air conditioning unit next to the plane. The vast majority of the time the airplane is either airborne usually at an air temperature of negative 50° f or at the gate at the airport. It doesn’t make business sense to carry the weight of an air conditioner for the relatively short time. The airplane is taxi.

        You are wrong. Airplanes very much do have air conditioners. The reason they pump cold air into the plane when it’s at the gate is so they don’t have to run the APU or the engines. It saves on both jet fuel and emissions.

        Almost all aircrafts have air conditioning. Even the small single cessna’s have air conditioning device.

        How do you think airplanes are pressurized at 35k ft and stay warm?
