Cabin crews perform their duty in the cabin. Typically there is no cabin in cargo aircraft. Cabin area is replaced by main deck and no passenger to service. I don't think airline will assign cabin crew to follow flight to serve pilots and license aircraft engineer (if any) onboard.
On commercial airliners the jet turbines are also used to cram air into small ducts (at very high pressure) which is mixed with recycled air and then bled back into the cabin through the air conditioning.

The majority are limited to 10,000 or 12,000 feet (the height where you must use oxygen and/or a pressurized cabin). That's not a law, and some people own aircraft that operate on the same rules as commercial airliners.
On modern airliners, the Cabin Manager (chief flight attendant) is often called the purser.
At altitudes above 10,000 feet there is not enough air for humans to breathe. Aircraft cabins are pressurized so the pressure is equal to that at about 7,000 feet. Commercial airliners fly at altitudes up to 40,000 feet.
So that the passenger and crew remain alive. At 40,000 feet a person with an oxygen mask breathing pure oxygen will have cognitive (thinking) problems. Pressurising the cabin removes the risk, discomfort and other issues with oxygen systems.
So the passengers can breathe. ----------------------------------------- You see, above a certain altitude, the air is so thin that it will not support human life.

At the high altitudes which airliners fly in, there is less dense. Since air is good for us humans, the cabin is pressurized in order to provide enough air to breathe.
It actually depends on in what environment the role of stewardess is undertaken. i.e. in airlines cabin crew who are tall have issue working in the aisles as aircrafts are so compact.
A cabin crew is the members of staff aboard a commercial aircraft, employed to ensure the safety and comfort of other passengers.

LOL they can fly in planes. Women are famous for being Cabin Crew
