I'm really wondering if this is one person posting bogus complaints against Delta because this one also doesn't add up.

The air conditioning works by simply bleeding some of the air into the cabin that goes into the front of the engine. It's done with differences in air pressure. Higher pressure is hotter than lower pressure.

However this same system is also what is used to pressurize the plane. Also, I don't recall the altitude, but it's about 6 or 8 thousand feet that there is a thermal layer where the air outside suddenly gets very cold.

Now, if the system was broken as claimed, then they would have had to have flown at about 9-10 thousand feet. They would not be able to above 10,000 because that is where the air gets too thin to breath. So they would have been flying unpressurized. However, because of the outside air temp. the inside would not have stayed the 90 degrees that it was on the ground.

And if PHX's info is correct, that they flew at 24,000 feet, then they system had to be working, otherwise you all would be dead right now. You cannot breath the air that high up. But that also means the pressure system was working, hence they were able to pump air into the cabin, and keep it cool.

Sorry, but this one doesn't hold water.
