But you also have cool air vent above your head. And they are pretty good with keeping people cool.
People who prefer warmer cabins don't have that luxury of space heaters in their seats...

You'll never get a temperature that's equally pleasant for 200 strangers bundled into a metal tube together. My boyfriend and I can't even agree on the AC in a car. The best everyone can do is ask the FA's to make you more comfortable, understanding of course that there's times when they can't or won't honor your request, and know your own personal comfort level then dress and pack accordingly. I'm always cold and I usually bring my own blanket; the fella is always warm and usually travels in short sleeves even in dead of winter. But in any group of 200 (or even 2) you'll find some that are roasting, some that are freezing and some that are just right.

Put me in the "Rather be cool than hot" camp!

I would love to know the conditions under which that study was conducted. I am perfectly happy to sleep in a 65 degree room - or even cooler - if I have a bed, pillows, and a 10-tog down duvet. Under ideal sleeping conditions, sure, cool is fine (the bigger issue is forcing yourself to get out of warm bed into cool air in the morning). On a plane, however, none of these ideal conditions apply: I do have a small down pillow I travel with that makes a big difference to how well I sleep on the plane, and I bundle up in the thin fleece blanket, two shirts, a Polartec jacket with hood, Polartec socks, and if I have to, a hat and a sweater - and sometimes I'm *still* cold. Some people just get cold when they're not moving. It's not a character flaw.

Insisting that those of us who are frequently cold on planes are wrong is really pointless. As someone else said, you're not going to get 200-300 people to agree, so you have to pick a middle-of-the-road temperature that's going to be tolerable for the biggest number of people. The outliers - which are who I suspect are mostly talking here - will have to adapt somehow.

See I disagree with this. The fact is that you can always add layers. You can only remove so many. The logical argument here trumps a democratic majority/middle ground approach.

How you gonna get 'democratic majority' on the plane? By voting or by asking people who are hot to press FA button, so they can count hot vs. cold people?

Makes sense on the ground but not so much in the air. Everyone's extra layers are in their luggage or at home. The casual traveler has a hard enough time getting their toothpaste into their Freedom baggies; the Art of Packing Extra Layers In Case You're Cold might be too much. Airplane blankets aren't coming back, which isn't a bad thing considering how germy those things have got to be.

I much prefer it cooler. BDL - CLT 11-24, cabin fluctuated in temp but lingurred on the warm side for a bit

I recall a thread from back in the day when US was charging for water... It seemed that more flights were warm, with anticipation that people would buy more.:)

I agree. Hot is better than cold!

+1

I travel with layers of course, but there are only so many I can put on pratically. I do realize I am always colder than the average person, not just on a plane. But I hate being too cold on a plane, very uncomfortable!

I have noticed that. I particularly remember one flight from BOS-PHL on a 190. The FA's were trying to balance the temp and just couldn't do it. One of them actually came on the PA and apologized and said, "We are working on the temperature in here, but apparently we can only either freeze meat or roast it, so we're doing our best". Got a good laugh out of everyone and lightened the mood.

On two of my flights yesterday it was 50/50.
DCA-LAS flight was nice and warm, but my LAS-DCA flight was cold.
Temperature in Vegas was around 40. At the end of the flight there was a lot of coughing and sneezing pax.
Best way to catch a cold is to be locked with sick people in the flying tube.

Slightly OT. My DCA-LAS flight was operated by West aircraft N818AW still with old first class seats. I thought that all interiors were replaced by now. They are much better then new first class seats.

The cool air vent was blowing hot air the other night.

It was probably SO cold in the cabin that you thought that the air vent is blowing hot air :D

what does that have to do with the cabin being hot or cold? being "cold" doesn't cause colds, either.

FWIW, most bacteria thrive in warm environments.

for those complaining about not having access to layers... bring a jacket! it doesn't count as a carry on...
