Mr Mac,
I hope you are right and I am wrong. I just think that in addition to the all the People saying they are loving home working and video calls (whether they mean it or not)
, there are also many who are going to use this as an excuse to permanently curb flights for environmental reasons. I wouldn't put it past some governments to raise air taxes to more or less force people to stay where they are. It will be dressed up as a mix of doing it for the environment, the "we can't go back to how things were" mindset and the fact they will want to promote "staycations" to boost their own economies.
