Finnair, the flag carrier for Finland, had previously announced on Tuesday that it would be canceling five of its weekly flights to Beijing (at the Beijing Daxing International Airport) and Nanjing through March 29. However, Finnair said it would “continue to operate daily to Beijing Capital Airport and to Shanghai, and twice a day to Hong Kong, and to Guangzhou twice a week.”

Air Canada is scaling back as well, canceling “select flights” to China to “better match capacity with expected demand.

“Air Canada currently operates 33 flights a week to China and the resulting capacity reduction is relatively small. Those customers who are affected will be notified and provided with alternate travel options,” the airline wrote in a statement to Fox News.

Meanwhile, among U.S. carriers, United Airlines confirmed on Tuesday that it had canceled some of its scheduled China-bound flights from San Francisco International Airport, Newark Liberty International Airport, Chicago O’Hare International Airport and Washington Dulles International Airport in Virginia for the first week of February. United is also waiving its change fees for some of its ticket holders who wish to change their flights to China.

“Due to a significant decline in demand for travel to China, we are suspending some flights between our hub cities and Beijing, Hong Kong and Shanghai beginning Feb. 1 through Feb. 8. We will continue to monitor the situation as it develops and will adjust our schedule as needed,” United said a statement to Fox News.

Concerns over the virus' fast-spreading nature have also prompted the CDC to increase staffing at 20 U.S. airports that have quarantine facilities, The Washington Post reported. Screenings initially began for travelers arriving from Hubei at just three airports — SFO, LAX and JFK — with additional screenings implemented at O'Hare in Chicago and Hartsfield Jackson in Atlanta.

On Monday, the U.S. State Department raised its China travel advisory from a Level 2 (Exercise Increased Caution) to a Level 3 (Reconsider Travel), citing the “novel coronavirus first identified in Wuhan, China.” The State Department had further issued a Level 4 advisory (Do Not Travel) for the entire Hubei province, the capital of which is Wuhan.

The U.S. Centers for Disease Control and Prevention (CDC) also issued a Level 3 warning to travelers, urging them to “avoid all non-essential travel to China.”
