“Now we’re boarding from the back of the aircraft to the front of the aircraft to minimize touch-points, and, for now, no one sits in the middle seat,” said Macagno, the managing director of Latin America, Caribbean and South Florida.

Macagno also said Delta Airlines is focusing on cleanliness from airport door to airline seat. To do so, planes are undergoing a “triple-layer cleaning” that involves electrostatic spray disinfection. The system turns disinfectant liquid into aerosols. A charge moves each droplet to surfaces.
