Airplanes need to have curtains to separate them from each other because there are different price classes. Different price classes have different groups of people in them, for example, first class has a lot of celebrities and successful people, etc. They prefer to keep their itineraries private and not be disturbed by passengers in other classes.

The flight attendants are also doing this to prevent some passengers from getting airsick when they smell the odor. Because there are a lot of passengers who usually get carsick and seasick, then they take the airplane, although there is no bumps on the ground, but also because of the catering Department of the odor of the stimulation and the phenomenon of airsickness. At this time, if the flight attendants can pull the curtain, it will be a lot friendlier to this kind of people, and also save a lot of trouble for the flight attendants. So the curtain is also to reduce the probability of airsickness of passengers on the airplane. In short, it is to block the various cabin, because we need to protect the privacy and safety of some special passengers, and pull the curtain can block the catering department of the odor, create a good environment in the cabin, but also reduce the occurrence of airsickness phenomenon.
