In the US, it is somewhat confusing on how each of the airlines and states are dealing with this pandemic. My son was told to fly to Dallas for work - one day event. Hotels were empty and restaurant closed in the hotel. The flights back to Boston were 100% full on American. Delta (who I usually fly) are restricting to 60% coach and 50% 1st class or so they say. I have guidance from work (same employer) that if I travel via air (not likely given the high level or permission required), 14 days self quarantine on arrival back home IF there is someone next to me or in the same seat in front of or behind me, in other words if we can't space 6 feet apart. This is entirely dependent upon state regs and guidance for folks in other states is completely different. I don't see how this is can possibly deter spread. It is utterly confusing.
