Free middle seats significantly reduce the risk of infection with corona on board a commercial aircraft. One comes to this conclusion Study the US Disease Control Agency CDC.

In simulations in short- and long-haul aircraft, the researchers found a reduction in the corona infection rate of 23 to 57 percent. The distance, air exchange and filter systems would prevent aerosols from spreading in the cabin. "If these standards are followed, most virus particles will be removed from a hearth within a few rows of seats," argued the experts. "The recirculated part of the air that flows to each passenger has passed through highly efficient particle air filters (HEPA filters)."
