Some people really live under the rock !π And are acting like a little kids - crying and throwing tantrums when their toy is taken away... Why would one be so desperate to try to come to Thailand as a tourist still this year and throw money away on booking a flights that most probably will not happen ?πππ
USA's population is huge - 370 mill for the size of the country - it's a lot, too much I would say. A lot of people have not so good living conditions. That's the reason for such high infection numbers.
I don't think travel will become more expensive as itself - some airlines already are fighting this rule of empty seats for distance purposes, they say some other measures need to be used. It will not become more expensive by the same very reason - not too many people will now grab their suitcases and start traveling, not because they cannot afford it but because it's just too much of a trouble to travel at the moment - restrictions, quarantines, doctors certificates, etc...
Hotels and resorts, when they are allowed to operate again - will have to lure people with good prices π
