Delta Air Lines first began fogging its aircraft in February when concerns about the spread of the coronavirus outside of China were growing, focusing on those coming from the Asia-Pacific region. //

Delta announced that its fogging measures will be expanded to nightly for every aircraft on April 1 and later in May to before every flight. //
