You can be quite comfortable in cold air, if there's a good radiant heat
source aimed at you. (Think bright sunny days in winter, for instance.) On
the other hand, I used to work in a shop with radiant heat, and it sucked.
The nominal air temp was 62, which was fine, but what would happen is you'd
open a door, drive a cold, snow covered car in, put it on the lift, and
stand under the car. The car got the benefit of the heater, and snow
melted, and dripped on you. You, on the other hand, got the benefit of
amazing radiant cooling from the frozen car, and got melt water dripped down
you back. I would have to work hard to make a heating system any less
pleasant. It's probably not as bad with airplanes.
