This is maybe a silly question, but something that has been bothering me for a while, and so I thought TA experts who really know airplanes might shed some light on this.
In 2010, my parents were on a roundtrip Air Transat flight (YUL to BSL). In both directions, they ended up being very hot on the plane. My mother tells of feeling almost sick from the heat, no fresh air, etc. The story even includes reports of people fainting from the heat. They were seated towards the front of the plane (but in regular economy), and apparently, the people in the back were completely freezing. Their conclusion is that the FA were increasing the heat for the back freezing passengers, while everyone in the front was dying (metaphorically) from the heat.
Now based on this SINGLE occurrence, they have now decided to always reserve seats at the back of planes on their future travels, because they are convinced the air is fresher in the back.
I've never openly contradicted their conclusions or decision of future seat choices, but I've always figured this might have been an isolated occurrence, maybe a problem with the ventilation or something?
My question to the board is two-fold:
1) Is there any truth to their belief that they are less likely to be hot if sitting in the back of the plane?
2) What kind of control over cabin temperature do FAs actually have anyway? Can their idea of FAs increasing the heat for freezing passengers in the back, causing them to feel even more heat in the front, have any kind of ground to stand on?
