In an early sign of hope for the largely shuttered travel industry, some countries are taking their first steps toward reopening to tourism.
In Europe, Slovenia last week proclaimed an end to its Covid-19 outbreak and reopened it borders to regional travelers. Any non-European Union residents must quarantine for two weeks upon entry.
Austria and Germany also began loosening controls over the weekend, opening border crossing points with France, Switzerland and Austria.
Italy said on Friday that it would open its borders to EU residents in June. And Greece said it hopes to reopen for international tourism on July 1.
Iceland said it will welcome tourists back on June 15, although travelers must agree to take a Covid-19 test on arrival or quarantine for two weeks.
In the Americas, some Mexico beach destinations are planning to open in June as well. And Southwest Airlines announced it will resume flights from several U.S. cities to Cancun.
Spain and Portugal have announced plans to open their beaches in June, although the countries haven’t yet laid out plans for how their borders might reopen.
The European Union has encouraged countries with similar rates of coronavirus infections and comparably strong healthcare systems to open borders with each other.
In other parts of the world some countries are also looking to regional “travel bubbles” as a first step toward reopening to tourism.
The Baltic countries of Estonia, Latvia and Lithuania Friday opened their borders to one another last week. And Australia and New Zealand, which have both had relatively mild outbreaks, are talking about a possible "trans-Tasman bubble", where people could go between Australia and New Zealand freely, and without quarantine, according to local media reports.
