The last time I went on an aircraft to fly across the country on business, I had the most uncomfortable flight going there! Thankfully it was not the same when I was coming back home. But going there there was easily an awful air conditioner on the plane. It was easily sizzling out as this is the start of the summer time months of the year. And the aircraft had little to no central heating plus air conditioner! The air conditioner was coming out of the little tube above everyone’s seat weaker than ever. It ended up getting so sizzling plus stuffy in the aircraft that they had to bring out a portable air conditioner system that they had on hand for emergencies. Which, I have to provide them credit for even having thought of that plus having a portable air conditioner system on board! That is not something that you usually hear of or see. So I think I was lucky in that aspect. But I have to tell you that even with their emergency portable air conditioner system that they blocked in, it was still an easily uncomfortable flight all together! The next time I have to fly somewhere I entirely hope that something cares about this not ever happening again. Because I need our indoor comfort at all times! More so when on an aircraft! And not to mention, I can not afford to fly first class. But even if I did, I do not think that would have made a difference whatsoever.
