But, is there an exact temperature that makes it too cold for a commercial airplane to fly? “There is not a specific temperature,” says Tom Haines, Senior Vice President of Media, Communications & Outreach at the Aircraft Owners and Pilots Association (AOPA).
Every plane has a different maximum operating temperature, depending on the weight, body and engines of the aircraft. For the Boeing 737, anything above 54 degrees Celsius (129.2 Fahrenheit) is a no-go.
