United Airlines says Hong Kong flights will now resume from April 24.

United Airlines said the airline is extending cancelations of flights to Hong Kong, which had been set to resume on February 21, and for flights to mainland China, that had been set to resume on March 28. Flights will resume starting April 24.

The US carrier made the annoucement late on Wednesday. Cancelations of all U.S. flights to China are extened through late April due to the coronavirus epidemic, Reuters reports.

With the announcement by Chicago-based United, all U.S. passenger carriers flying to China have now canceled flights into late April. Carriers say part of the reason is a dramatic drop-off in demand.

United normally operates roughly 12 flights per day from the United States to mainland China and Hong Kong.

American Airlines Group Inc, the largest U.S. carrier, said on Tuesday it was extending the suspension of its China and Hong Kong flights through April 24, amid reduced demand due to the coronavirus outbreak. The carrier had earlier suspended its China and Hong Kong flights until March 27.
