First thing people should know is that the two expert agencies, the World Health Organization and CDC - Centers for Disease Control, have reviewed the environment, and neither have recommended any restrictions whatsoever on travel. The air in a cabin of an airplane is better, more proved, because of hospital-grade HEPA filters and side by side circulation, that it is in the vast majority of public buildings in the United States to include schools and offices. So don't be concerned by getting on an airplane. We have hands sanitizers, and soap in the lavatories on all of our planes, and we encourage people, as others do, to wash their hands frequently that cover their mouth when they cough, and take just normal everyday common sense protections and provisions that your mom would tell you when you were going to school. The real key here I think is for all citizens to understand that if you feel not well, stay home, whether it's school, whether it's workplace, whether it's travel, just stay home. Self policing can do more to prevent the spread of this disease than almost anything.
