As a longtime germophobe, who is quite sure I have caught trip-ruining flu's and colds on multiple occasions from inconsiderate passengers on flights, hysteria could lead to some real improvements this time. Screening of sick passengers, extreme filtering of recirculated air, roomier airports rather than packing a dozen gates 12 feet apart at the end of the building (LAX), and while I'm dreaming, some social distancing between seats. They can make everyone wear full-on gas masks the entire trip. Still working on how to deal with bathrooms. At the very least, airlines can change those shitty change/refund policies that keep people from delaying their trip when they get sick.
