A Pew Center study found that more than 90% of the world's population - 7.1 billion people - lived in April in countries subject to travel restrictions on people from abroad linked to the spread of the Coronavirus.
While domestic closures are beginning to decline in many countries now, the international travel downtime is likely to last longer, as countries continue to focus on staving off the second wave of infection.
Professor Lindsay Wiley of the University of Washington School of Law said: "Travel and immigration to work, study and seek asylum will be disrupted for much longer in an unprecedented way in our lives."
And prominent figures in the aviation industry also said they expect it will take several years before passenger demand returns to its 2019 levels.
Solution scenario
Greek Tourism Minister Harry Theoharis told the Guardian newspaper that although the country is desperate to protect its economy, it is almost certain that flights to its islands and beaches will definitely be interrupted this year.
However, countries that have acted quickly to control the disease are beginning to explore ways to reopen a limited number of their citizens to travel without restrictions, as in New Zealand and Australia.
Nine countries are scattered around the world, but united in their successful treatment of the virus are also actively seeking ways to form bubbles or travel lanes, widening an unlikely alliance.
The leaders of Austria, Greece, Norway, Denmark, the Czech Republic, Singapore, Australia and New Zealand agreed at their second meeting by rushing to discuss solutions that save the economy, that with the start of all easing restrictions, after the successful experience of controlling the disease in some of these countries, low rates of infection can be benefited by creating what It is called "safe area tourism", with the hope that this will be implemented as of July.
The European Commission is expected to recommend a three-stage approach to reopening the border, bringing together member states that share "similar public risk rates".

However, any reopening will be gradual, with the authorities preparing to close again if the virus reappears.
On the other hand, the United Kingdom has set the scenario of its vision regarding the return of travel. If the incubation period requires two weeks of isolation from arrival at the destination, and two weeks after arriving in the countries of departure, this means a full month of sanitary isolation, which effectively reduces the possibilities of commercial travel. Tourist.
Economic cost requires restructuring
While partial or total closure of borders is in the interest of countries in terms of health, closings come at a high economic cost to countries dependent on tourism or other types of travel, such as international students traveling to university education, and this economic burden may assist in attempts to accelerate the reopening the border.
For places like Hawaii, Iceland, or New Zealand, these countries need to restructure the economy with deliberately a large form of tourism.
Travel solutions and alternatives before vaccine development
Other options for trying to restore travel before pre-vaccination development include the need to carry out antibody tests for the virus before travel, which are antibodies that the body produces after infection and which may amount to an immunity to the body from infection again to prove immunity, or tests for the disease itself to prevent infected people from traveling.
As with some countries that allow yellow fever vaccination certificate holders to enter it, traveling under Corona will require a passport of immunity that proves that the virus is free and immune to it.
This is something that researchers are unlikely to have available soon, as the World Health Organization has warned that detection and detection of antibodies alone should not be a basis for "immunity", because scientists do not know how much antibody will protect people from infection again.
Change the shape of travel
At a time when the impact of aviation on the increase of electronic emissions in the atmosphere provoked anxiety after the results of climate improvement appeared after most aviation operations stopped, some countries are adopting permanent policies to protect the environment and reduce the carbon footprint,
More than 4 billion people are used to air travel around the world, according to a sociology professor at the University of Lancasterto, whose research is based on reducing carbon emissions from transport.
Today businessmen accomplish most of their meetings via video calls, and business analysts suggest that 25 to 30% of business-related travel be replaced by other methods such as video calls and meetings across virtual spaces permanently by 2021.
As comprehensive international travel for business appeared just two decades ago, customs can change dramatically again.
