My recent american flight (yesterday) was absolutely freezing. Many people were wearing winter coats, but as it was a flight to phoenix, not all of us were prepared to be refrigerated for * hours. I spoke to the flight attendant multiple times (first to ask if the heat had broken because I could think of no other reason someone would keep it that cold,) but they raised it *, maybe * degrees. I still could not feel my hands or stop my teeth from chattering. *I am not looking for anything specific, though some type of voucher or miles would be appreciated and make me more likely to give American another try. *Mostly I am wanting to know if there are any policies in place regarding temperature, because I do not feel like I would ever choose American again knowing I might be kept this uncomfortable for hours again. *I am a frequent flyer on american as well as other airlines and have never been this uncomfortable on a flight or had my flight attendants disregard my concerns in this way.
