 Leather seats are more costly than traditional cloth seats.Even so, several airlines, including low-cost carriers, choose leather not only to present a more "luxurious" product, but also because such seats are easier to clean and prevent spilt liquids from soaking through to the padding for reduced turnaround issues.In the fairly early days of aviation, airline seats were typically of earthy and soft colors such as light browns and gray, which were intended to calm the passengers.
