Yea I was recently on a flight and the pilots had the PC air but it was blowing hot air. It was so hot you felt like you were actually breathing hot air like when you walk around PHX in the middle of August. The FA was sweating yet she wasn’t doing anything. Totally clueless. The pilots had their feet up probably playing candy crush or browsing APC... they finally disconnected when the doors closed. This whole time the APU was on too but not selected. Please pay attention.
