Just to bring a bit of positive vibes, here in Greece tourism started around June with very small numbers for the first weeks. But we are now practically back to 2019 numbers.All within 2 months!
All these although the 4th wave (thanks to delta variant) is here, bringing a quite big increase of covid daily cases, but not so much on fatalities. Keep in mind that "only" about 55% of the population is vaccinated (and the other 45% is mostly unwilling to do so) and that daily measures have practically almost been lifted except for some activities like traveling that require vaccination certificate or negative test.
Another promising thing: after 2 years of lockdowns, restrictions etc, visitors that finally come are willing to spend much more than before!
It will take some more time for countries like Indonesia, but recovery IS coming.
My estimate: by end of the year/early 2022 things will be getting much better for long haul international traveling and by mid 2022 things will be back to almost normal even for countries like Indonesia that now are struggling.
All the best.
