Interesting concepts and ideas on how the international airline future will look. My feeling is that if a vaccine is developed in the next 6 months we will return to air travel procedures much as they were previously. We will all acknowledge the health dangers but lowest price will prevail unfortunately.
If we stay grounded more than 6 months it will be a whole new ballgame. Business and tourist passengers will have gotten used to not flying and the whole experience may need to be justified as a safe and affordable transport option.
