26 March 2020: Adhering to the strict guidelines set by Centre for Disease Control and Prevention (CDC) and the World Health Organization (WHO) the team at Southwest Airlines routinely undergo more than six hours of aircraft cleaning every night.
The enhanced cleaning procedures include use of an EPA-approved, hospital-grade disinfectant to address human touch points across the passenger cabin, lavatories, and flight deck.
Besides this, all the aircraft are equipped with HEPA (High Efficiency Particulate Air) filter, which filters out re-circulated air on-board each plane to remove airborne particles. (HEPA filters are also used in hospitals to provide patients with clean air.)
