A little overly pessimistic there somewhat. Whilst i don’t think it will be a normal summer in terms of numbers, I’m confident there will be a summer season in some form or another. I simply cannot see this summer being worse than last when the most vulnerable across Europe will have been vaccinated. I don’t think the public will stand for it and there would be intense pressure on governments from the airlines and tourism industries. The current theatre of quarantine is the result of a government reacting to pressure, come summer that pressure will swing quite the opposite way should the vaccination programme still be progressing at pace.
A failure to have any sort of summer this year will be absolute decimation for the airlines, let alone a disrupted summer 2022 which would be apocalyptic.
