European nations eased border controls from June 15

European nations eased border controls on Sunday as the number of coronavirus cases declined after three months of lockdown, but Spain's continued closure, a patchwork of quarantine rules and remote-working mean pre-crisis travel levels are a way off.

Greek airports allowed more international flights as the country sought to salvage its summer, German tourists flocking to neighboring Denmark caused an 8km queue and Italians popped into France to buy lottery scratch cards.

In the Belgian village of Macquenoise, tabac stores did brisk trade as French citizens streamed across the border to buy cheaper tobacco after suffering higher prices at home since mid-March.

"It's worth the effort," said Nadege Caplain, making an early-morning 200km round trip to buy cigarettes for her and her family.

The Schengen area of 22 EU countries plus Iceland, Liechtenstein, Norway and Switzerland operates control-free crossings. But for the past three months they have been mostly closed to all but goods traffic and cross-border commuters.

European officials hope the lifting of internal border controls will allow a gradual reopening to other countries from July and resuscitate a tourism industry that flatlined during the lockdown.

Tourism and recreation make up almost 10 percent the EU economy and even more in the Mediterranean countries, some of which were hit hardest by the pandemic.

In Greece, passengers arriving from airports deemed high-risk by the EU's aviation safety agency will be tested for the coronavirus and quarantined up to 14 days, depending on the result. Restrictions remain for passengers from Britain and Turkey. Arrivals from other airports will be randomly tested.

It will, however, not be a return to unfettered travel for the Schengen area's 420 million inhabitants.

Spain will allow no foreign tourists until June 21, with exceptions for some Spanish islands.

Elsewhere, the right to travel will depend on where you live and where you are going. The Czech Republic has a traffic-light system, barring entry for tourists from 'orange' or 'red' countries such as Portugal and Sweden.

Denmark will allow in tourists from Iceland, Germany and Norway, but notably not Sweden, on condition they book at least six nights' accommodation.

Britain's two-week quarantine for visitors means Britons will face the same confinement in France.

Before the crisis, an average of 3.5 million people crossed an internal EU border every day, according to a 2019 European Parliament report, some 1.7 million of them commuters. Many of the latter are now working from home, while continued restrictions and health concerns are expected to curb tourism and business travel.

At Brussels Airport, day one of the reopening will see around 60 flights operating, 10 percent of normal.
