ANA Holdings Inc. have said that seat reservations for its flights from China to Japan next month have halved from a year earlier, due to the spread of a deadly pneumonia-causing virus.

ANA said reservations for its flights from Japan to China have decreased by about 40 percent, with an executive of the company expressing concern that demand for cargo will likely also fall if the outbreak of the new coronavirus leads to a slowdown of the global economy.

But ANA said it was too soon to predict the impact of the virus outbreak on earnings, since its magnitude and duration remain unclear.
