We are waiting for a thorough, rigorous, enforced proposal from the airlines that:
- guarantees that we will not be infected,
- makes us believe the guarantee.
Wow, if you can ever get a guarantee like that from an airline, I'll be amazed! You can't get a guarantee that you'll arrive without being involved in an accident, nor that you baggage will arrive to the same place you do, so I can't imagine a health guarantee, for which evidence will only exist days after you've left the flight. Until this past February, I regularly flew through AMS KLM business class. I got off a regional KLM flight, with a coughing person in the back. How happy I was to be sitting in row 1. 'Plane stops on a stand, and we all board a bus to the terminal. Who's sitting beside me on the bus? Coughing guy... So much for my buying business class to increase my distance from other people!
If you want a guarantee, buy the plane! I now do my local business travel in one of my planes - guarantee no infectious person in the plane with me!
