The temperature of the atmosphere sinks with an average of 0.65 degrees centigrade per 100 m of altitude, which is about 2 degrees per 1,000 feet. (pilots use mostly feet of altitude).
But dry air sinks with 1 degree per 100 meter and wet air (saturated with moisture) sinks with only 0.5 degree per 100 m. The reason being that moist air must give away energy in order to condense to water droplets.
That difference of cooling between wet and dry air is the reason we have frontal low pressures and thunderstorms.

Most air except near the poles in winter is warmer than that at ground level. It gets cooler as you go up until you get to 85,000 feet where it starts getting warmer. It is often 50 to 100 degrees below zero at very high altitudes like 40,000 feet in a jetliner.

The temperature decreases as you go up in the atmosphere.so,as you go up,zero degree celcius reaches at a particular level which is called 'freezing level' The average height of this freezing level is about 5.5 Kms above the earth's surface in tropics.Of course, in poles this freezing level may be on the surace itself on most of the occasions.
So, the temperature at higher levels may be both above and below zero degree celcius in tropics.But, in poles usually the temperature is below zero degree at higher levels in most part of the year.

depends on the height but the higher you go the colder it is
as for 0 degrees C I think aircraft like jumbos fly high enough for 2 or 3 degrees

how high above the ground are you talking?
