“I made no comments about what the cruise lines were doing with their ventilation systems...My comment was about how airlines are dealing with and filtering the air they circulate.”
So you CANNOT backup your claim regarding air filtering on aircraft. Sorry, but I don’t care if you were STUPID enough to lose your shirt on the obvious shutdown of travel (or not), but if you make a claim here, PLEASE back it up.
I’m looking for FAA Regulations or Airline announcements about how they protect against viruses, and BEFORE January 23, 2020.
If you have none, then sorry for your retirement.
