I have a commercial pilot rating, and travelled on business for years. The trust needed to travel in the pre-SARS-2 days will never fully return. We got a glimpse of that a decade ago when an American had a virulent form of TB in Italy and had his passport revoked by the US govt. But corona is a 10/10 on the disruption scale. All I can suggest is that Boeing and Airbus put their heads together and figure out what it means to protect pax from a pandemic It might mean hepafilters, more bleed air and pax wearing masks. FYI: the recent fuel-efficient airliners appear to re-circulate cabin air far more than previous designs, for fuel efficiency reasons. Engine bleed air used to be injected into the cabin, but recirculating is several percentage points more efficiet. And lethal if even one pax is sick.
