so many line pilots don’t commute or DH very much. They have no idea how stagnant and hot it gets in the back of the plane waiting to hook up ground air. And being selfish pilots they get GPU connected and split instead of making sure row 30 is getting air. This is the main problem with not running the APU when parking. Well this and sucking up air hoses or people. I don’t leave or stop cooling until ground air is connected or more than 2/3 of the airplane is empty.
