I live in the south so I’m used to pretty warm hot plus cold temperatures.
Occasionally though, the heat does get to me.
I did a corporation trip plus went to an even further southern state. It was ridiculously warm there the entire time. I was lucky that our hotel, corporation meetings plus meals all had a/c. I never had to sweat to death. That is until I got onto the plane. I was in a state that was over 100 degrees plus flying to our home state that was showing hot plus cold temperatures in the high 90s. Obviously the plane should have used a/c for its passengers. Something went wrong with the plane cooling system. There was none. It was funny at first watching people board the plane plus instantaneously adjust their air vent. Some people were downright frantic to try plus get cooling, then nothing came out of the air vent, no airflow was possible. The whole plane ride was awful. Not only was the air temperature high, but the sunshine was blaring into the plane as well. It had to be over 100 degrees on the plane. The lack of cooling made everyone sweaty, odory beasts too. Of course I was in a middle seat crammed between 2 genuinely moist seatmates. I was so ecstatic to arrive to our hometown airport because I knew there would be AC. It was the longest, most horrible plane ride of our life! Cooling on a plane can make it awful or make it a pleasant experience. It seems the lack of A/C is the same.
