Kenny,
Pacific routes are less than 10% of Uniteds Intl routes. I just checked loads to some Euro destinations and while lower than normal the aircraft are far from Empty. South America makes up a huge chunck of international traffic too.
Cases are 444 in the USA at the moment. A pandemic it isnt in the USA. People get panicked by the media telling them they may die. Comments like yours fuel this panic with "its going to be bad for a long time".
When Spanish Flu came through my country in 1919, 5 million people were infected over 9 months. The death rate was 0.008%. With modern medicine we have now that rate would have been considerably less.
On Kenny's advice I am off to buy toilet paper.
