They suspended all flights including out of the country and apparently domesticWhat makes you think it will earlier? 01SEP is four months away. Are the facts already indicating that countries like the US and Brazil will have the virus under control by then so that Argentina would not view travellers coming FROM the US or Brazil as a health risk? It was only a month ago where the majority of cases in Argentina were imported, most of them coming from the US and Europe - which had significantly less cases than they do today.... all it takes is one idiot breaking their quarantine to make all these weeks we are spending in lockdown wasted and go right back to square one.
Most European leaders have said they will be closed to Non-Schengen travellers until at least September.
