The landscape here is vast though. Air travel is only one component. These resorts (Hawaii, Mexico, Caribbean, Greece, Spain, etc) won’t survive two years of this. Four and five star hotels in Rome, Paris, or Barcelona? You can figure by late 2021....half of them might be entirely shutdown for a while. Same story for the cruise ship business.
With the vaccine business, I’m not convinced that it’ll be effective against ‘all’ versions of Covid-19.
The years after WW2 will be looked on the golden years of the travel industry. It it a virus from a Chinese laboratory to end it. It is amazing it lasted so long given the history of pandemics throughout human history. Even is a somewhat effective vaccine is developed travel on an in scale will be curtailed for the foreseeable future.
