This vaccination 'certificate' will open travel in Europe this summer

Our travel elves have been working around the clock to put together explainers on all the latest twists and turns in travel guidance.

Celebrity Millennium – the first major cruise ship allowing American passengers since the pandemic began – set off last weekend from Sint Maarten. Its first port of call was Barbados, which is now welcoming fully vaccinated travelers.

However, it wasn’t all plain sailing. Two guests had to be put in isolation after testing positive for Covid-19 in required end-of-cruise testing. And in in the Mediterranean this week, two passengers also tested positive for Covid on the MSC Seaside cruise ship.

Catch you all next Saturday for another travel round-up.

It’ll depart from Florida in May 2022 with a select 500 guests on board a 2,800-passenger ship. However, the most on-brand sitcom-meets-cruise adventure is still “Golden Fan at Seas,” a celebration of “The Golden Girls,” which is also set to return next year.

Luxury barging specialist European Waterways plans to resume barge cruises this June. It serves nine countries, including France, Germany, Holland and Italy.

Meanwhile, Uniworld Boutique River Cruises will resume operations on June 20 with a range of itineraries in Italy, Portugal and France.

The EU has a white list of countries from which nonessential travel into the bloc is approved: Israel, New Zealand, Rwanda, Singapore, South Korea, Thailand, Japan and Australia.

While the European Union is trying to create more universal requirements for tourism, conditions of entry differ from country to country.

Spain opened to vaccinated travelers from outside the EU on June 7 while France opened in international travelers on June 9 (the same day as it resumed indoor dining and the national curfew moved to 11 p.m.)

Those on France’s “green list” – vaccinated travelers from the European Union, Australia, South Korea, Israel, Japan, Lebanon, New Zealand and Singapore – can enter restriction-free. Nonvaccinated travelers will need to do a Covid test.

Vaccinated travelers from the “orange list” – which includes the US and the UK – will need to do a test, while the unvaccinated will be allowed in only for essential purposes. United Airlines will resume nonstop flights from Washington Dulles Airport to Paris Charles De Gaulle on July 1.

Denmark has also opened to fully vaccinated travelers from the UK and the US and its neighbor Norway is letting the fully vaccinated skip quarantine.

All foreign tourists can now visit Greece without the need for quarantine on arrival, provided they have a negative PCR test. The government plans to declare 80 islands – including most of the country’s top tourism destinations – Covid-safe by the end of June.

The island of Cyprus is open to vaccinated travelers from 65 countries, including the US and the UK.

However, there is some good news for fans of sheep-strewn archipelagos. Atlantic Airways is starting direct flights from Edinburgh to the Faroe Islands on July 1 – although at £308 ($406) per person return, it’s not cheap for a short hop.

The islands feature in the hotly anticipated and long delayed James Bond movie “No Time to Die,” coming later this year, and a new Sightseeing Tour visits the key locations. Keep your eyes closed to avoid spoilers.
