It does seem that the airline industry is in denial.
As Fergusd has pointed out, business travel is drastically curtailed and anecdotally I can testify that finance industry professionals think this is not likely to changed this year.
As for leisure travel, it is staggering trying to deal with quarantines and medical insurance issues, not to mention the impact of increasing global tensions.
A system reset appears inevitable once the current wave of panic stimulus funding is spent. As is, airlines the world over look to become government wards once again.
Is anyone offering any coherent proposals to wind up in a better place?
