Delta and American Airlines on Friday (January 31) both suspended lights from the U.S. to mainland China, citing the continued spread of the coronavirus.
The two are the first major U.S. carriers to temporarily halt operations over the outbreak, joining Air France KLM, British Airways, Lufthansa and Virgin Atlantic.
And the move comes a day after after American Airlines' pilots went so far as to file a lawsuit seeking an immediate halt to flights.
The airlines' action follow a State Department advisory urging Americans not to travel to China.
On Thursday, the World Health Organization this week declared the virus a global emergency.
