I have no idea what has been written here, but for me discs fly further with less resistance, period. The thinner the air, the further they go. This is the same in ball golf, the thinner the air the further the ball goes.
The thicker the air the more list the wing can create, and thus the more parasistic drag. The thinner the air the less lift and LESS DRAG (my guess this is why you see all these World Record throwers throwing relatively slow giding discs at elevation for their records). I played with a guy the other day that said he just got back from playing in the mountains in California, he said everyone just threw putters.
This density/lift coorelation also explains why a disc will be less stable in thinner air. The wing is not as effective in thinner air. Thus, the NOTCH on the bottom wing of your Teebird is not as effective (like the notch got smaller). This is the part of the wing that makes the disc stable. So, thinner air equals less stability for normally stable discs (typically).
There are several factors that effect air density. Elevation, humidity, air temperature, ground temperature. I have a density meter and have been taking readings for some time (I fly model airplanes in aerobatics competition). When the air is thinner, wings and props work far less effective. We see "density altitudes" like you might see in Colorado in the summer in Dallas over asphalt.
humidity more=thinner (more water less air)
air temperature higher = thinner
ground temperatutre higher = thinner
Now, there may be an explanation as to someone making the assumption that thicker air results in less stability. The speed of the air has more effect at higher densities. In other words, the wind becomes much more effective at higher densities. A winter 5 mph headwind will seem like a summer 10 mph headwind to your disc. So your disc might flip into a headwind in the winter that would not flip your disc in the summer.
