Are you suggesting that International numbers will be the same in two years ? , say April 2022
Not even starting international until 2021 , allow that to slip a couple of months , so from nothing to everything in 14 months
I don't want to rain on anyone's parade & we all want to see this come back asap
But two years means everything goes on rails , vaccine developed in best case time frame , then manufactured and given to 7 B people
, no second wave or hiccup of any kind & also assuming that people won't be scared to travel internationally & there will be the same demand from business & capacity to pay
I reckon getting back to half pre-covid after three years would be a great result
