Do you find that the airplane cabin are often very warm? I have often taken overnight First Class in the nose or upper deck and Business Class on the main deck and upper deck and I sleep a lot and the cabin becomes very warm and hot, not humid but a hot hot. I have asked them to turn it down, but no one else seems to complain and the temperature never seems to go down. When I fly on the upper deck next to the doors it is too cold. Does anyone else find this true?

Oh man, is this a sore spot for me! This is the oldest Flight Attendant trick in the book (and even dates back to train travel)! Some lazy FAs purposefully crank up the temp as they know it makes most passengers sleepy and sends them to la-la land which makes their job easier no longer having to serve awake and demanding passengers.

Pan Am FAs were notorious for this practice. I used to beg them to turn down the heat. One actually told me some passengers complained of cold. I told her, "Hey, they can put on more clothes or blankets, but what do you want me to do...strip down naked!?"

I can't sleep on a plane due to claustrophobia, and heat severely intensifies this condition.

I don't encounter this much anymore. But when it happens I keep on 'em until the turn it down.

Temperature sensitivity is very subjective. Most women are cold, especially older. Due to low metabolism and low thyroid function.

The FA's and Capt can not argue with a true temperature reading. That is why the Casio wrist watch with temperature readout is so valuable. They ever question the temp when I show it to them. Hot or cold!

Yes, the nose is colder! And by the doors! It is the drafty air conditioning that is more of a problem.

If it's too hot near the nose of the plane, then try sitting toward the back where aerodynamic friction does not warm up the fuselage so much.

I can't agree with you more - it is overwhelmingly warm on most planes. I must be the opposite of most though, because the warmer it gets - the less I am able to sleep!

Same here ... I can't sleep in the heat. And I have found in the past few years it seems that more planes are warm. Sometimes on the 777, the flight attendants are even surprised how much the temp has "creeped up" when they go to use the screen thermostat/control to cool it off. Yet I see people bunched up in blankets while I'm uncomfortably warm.

You would think airlines (management) would want the cabin temperature to be lower, not hotter.

Fresh air has to be heated by the engines, which uses more fuel. A hotter cabin means more fuel wasted.

Given the choice between a cold cabin with fresh air or a warm cabin with stale air (i.e., same fuel consumption), I'll take a blanket, please!

Hotter air is more drying to the lung tissue in the already low humidity of the cabin. That makes for LOWER oxygen transfer from the air through the lung tissue into the blood stream and the rest of the body. When you find you are getting short of breath or gasping, then the oxygen levels are TOO low. Recycling the air builds up ozone as well.

Does the Clean Air Act apply to airplane cabins? I doubt the standards could be met.

68�F (20�) is my "neither hot nor cold" point; ideal cabin temperature range is 66�F (~19�C) - 72�F (~22�C). Warmer than that, I have a hard time falling asleep (even if I want to). 76�F (~24�C) and above makes me extremely uncomfortable. If it's cold, all I need is a blanket to make me happy. If it's hot, I'll complain to the FAs.

EPS recommends: Bright Backlight Travel Alarm Clock With Temperature from Brookstone, item number B218917.

That Brookstone Travel Clock is a beauty, but I don't know how to use it on a plane or where to put it.
Until I got my first Casio Temperature wrist watch, I would have surely added it to my collection. I still might for the Bathroom!
